无烟烟草使用者将NNK剂量转化为NNAL的百分比尚无文献数据。本研究中,15名男性受试者在将2克无烟烟草置于脸颊和牙龈之间30分钟之前,已经戒除烟草使用3周。随后他们继续禁烟,并收集连续三天的24小时尿液样本。测定使用前后烟草中NNK的量以及唾液中NNK的量。据此计算的NNK剂量与接下来72小时内排泄的总NNAL量进行了比较。结合先前的药代动力学数据,这些数据显示无烟烟草使用者将NNK转化为总NNAL的百分比大约为14%至17%。这个数字可以用来计算无烟烟草使用者每天接触NNK的量(大约6微克)。本研究结果还表明,NNK在无烟烟草使用者体内的主要代谢途径是代谢激活为能与DNA反应的中间产物。
NNK uptake by measurement of the urinary metabolites 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol and its glucuronides (total NNAL) has been reported in many studies, but there are no data in the literature on the percentage of the NNK dose that is converted to NNAL in smokeless tobacco users. ... 15 male subjects abstained from tobacco use for 3 weeks before placing 2 g smokeless tobacco between their cheeks and gums for 30 min. They then continued abstinence and collected three consecutive 24-hr urine samples. The amount of NNK in the tobacco before and after use was determined along with the amount in expectorated saliva. The NNK dose thus calculated was compared with the amount of total NNAL excreted in the next 72 hr. These data, taken together with previous pharmacokinetic data, show that the percent conversion of NNK to total NNAL in smokeless tobacco users is approximately 14% to 17%. This figure can be used to calculate daily exposure to NNK in smokeless tobacco users ( approximately 6 ug). The results of this study also indicate that metabolic activation of NNK to intermediates that can react with DNA is its major pathway of metabolism in smokeless tobacco users.

NNK可以转化为吡啶氧化产物4-(甲基亚硝基氨基)-1-[3-(6-羟基吡啶基)]-1-丁酮(6-HONNK)和NNK-N-过氧化物。NNK的脱硝化随后氧化产生麦斯米。NNK可以替代烟酰胺在NADP+或NADPH中,生成NNK腺苷二磷酸((NNK)ADP+)和(NNK)ADPH(还原形式)。NNK的羰基还原产生NNAL,NNAL可以通过葡萄糖醛酸化结合形成四种NNAL-Gluc对映异构体:两种4-(甲基亚硝基氨基)-1-(3-吡啶基)-1-(O-β-D-葡萄糖醛酸基)丁烷(NNAL-O-Gluc)异构体和两种4-(甲基亚硝基氨基)-1-(3-吡啶基-N-β-D-葡萄糖醛酸基)-1-丁醇内盐(NNAL-N-Gluc)异构体。NNAL还转化为NNAL-N-过氧化物和NNAL(ADP+)。
NNK can be converted to the pyridine oxidation products 4-(methylnitrosamino)-1-[3- (6-hydroxypyridyl)]-1-butanone (6-HONNK) and NNK-N-oxide. Denitrosation of NNK followed by oxidation produces myosmine. NNK can replace nicotinamide in NADP+ or NADPH, to yield NNK adenosine dinucleotide phosphate ((NNK)ADP+) and (NNK)ADPH (reduced form). Carbonyl reduction of NNK produces NNAL which can be conjugated by glucuronidation giving four diastereomers of NNAL-Gluc: two isomers of 4- (methylnitrosamino)-1-(3-pyridyl)-1-(O-beta-D-glucopyranuronosyl)butane (NNAL-O-Gluc) and two isomers of 4-(methylnitrosamino)-1-(3-pyridyl-N-beta-D-glucopyranuronosyl)-1- butanolonium inner salt (NNAL-N-Gluc). NNAL is also converted to NNAL-N-oxide and NNAL(ADP+).

NNK和4-(甲基亚硝氨基)-1-(3-吡啶基)-1-丁醇(NNAL)的α-羟基化导致DNA和血红蛋白加合物。NNK甲基组的羟基化产生4-(羟甲基亚硝氨基)-1-(3-吡啶基)-1-丁酮(alpha-HOMeNNK),它可以作为葡萄糖醛酸苷,alpha-HOMeNNK-葡萄糖醛酸苷。alpha-HOMeNNK自发分解为4-氧代-4-(3-吡啶基)-1-丁烷二氮氧化物(POB-DZH)和甲醛。POB-DZH与水反应生成4-羟基-1-(3-吡啶基)-1-丁酮(HPB),它可以作为其葡萄糖醛酸苷,HPB-葡萄糖醛酸苷。POB-DZH还与DNA和血红蛋白反应,产生一系列加合物。NNK亚甲基组的α-羟基化产生4-(甲基亚硝氨基)-1-(3-吡啶基)-1-(4-羟基)丁酮(alpha-HOMethyleneNNK)。这种代谢物自发分解为4-(3-吡啶基)-4-氧代丁醛(酮醛)和甲烷二氮氧化物(Me-DZH)。酮醛进一步代谢为4-(3-吡啶基)-4-氧代丁酸(酮酸),后者可转化为4-羟基-4-(3-吡啶基)丁酸(羟基酸)。Me-DZH与水反应生成甲醇,并与DNA反应产生甲基加合物,如图2和图5所示。NNAL类似地在它的亚甲基组上进行α-羟基化,产生4-(甲基亚硝氨基)-1-(3-吡啶基)-1-(4-羟基)丁醇(alpha-HOMethyleneNNAL),并在其甲基组上产生4-(羟甲基亚硝氨基)-1-(3-吡啶基)-1-丁醇(alpha-HOMeNNAL)。Alpha-HOMethyleneNNAL自发分解为Me-DZH和5-(3-吡啶基)-2-羟基四氢呋喃(乳糖),后者可以转化为羟基酸。Alpha-HOMeNNAL自发分解为4-羟基-4-(3-吡啶基)-1-丁烷二氮氧化物(PHB-DZH)和甲醛。PHB-DZH与水反应生成4-(3-吡啶基)丁烷-1,4-二醇(二醇),环化为2-(3-吡啶基)四氢呋喃(吡啶THF),并与DNA和血红蛋白反应产生加合物。
Alpha-Hydroxylation of NNK and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) leads to DNA and hemoglobin adducts. Hydroxylation of the NNK methyl group gives 4-(hydroxymethylnitrosamino)-1-(3-pyridyl)-1-butanone (alpha-HOMeNNK) which can be conjugated as a glucuronide, alpha-HOMeNNK-Gluc. -HOMeNNK spontaneously decomposes to 4-oxo-4-(3-pyridyl)-1-butanediazohydroxide (POB-DZH) and formaldehyde. POB-DZH reacts with water to give 4-hydroxy-1-(3-pyridyl)- 1-butanone (HPB) which can be conjugated as its glucuronide, HPB-Gluc. POB-DZH also reacts with DNA and haemoglobin to produce a series of adducts. Alpha-Hydroxylation of the NNK methylene group produces 4-(methylnitrosamino)-1-(3-pyridyl)- 1-(4-hydroxy)butanone (alpha-HOMethyleneNNK). This metabolite spontaneously decomposes to 4-(3-pyridyl)-4-oxobutanal (keto aldehyde) and methanediazohydroxide (Me- DZH). Keto aldehyde is further metabolized to 4-(3-pyridyl)-4-oxobutanoic acid (keto acid) which in turn can be converted to 4-hydroxy-4-(3-pyridyl)butanoic acid (hydroxy acid). Me-DZH reacts with water to yield methanol and with DNA to produce methyl adducts as shown in Figures 2 and 5. NNAL similarly undergoes alpha-hydroxylation at its methylene group to yield 4-(methylnitrosamino)-1-(3-pyridyl)-1-(4-hydroxy)butanol (alpha-HOMethyleneNNAL) and at its methyl group to yield 4-(hydroxymethylnitrosamino)-1-(3-pyridyl)- 1-butanol (alpha-HOMeNNAL). Alpha-HOMethyleneNNAL spontaneously decomposes to Me- DZH and 5-(3-pyridyl)-2-hydroxytetrahydrofuran (lactol), which can be converted to hydroxy acid. Alpha-HOMeNNAL spontaneously decomposes to 4-hydroxy-4-(3-pyridyl)-1- butanediazohydroxide (PHB-DZH) and formaldehyde. PHB-DZH reacts with water to yield 4-(3-pyridyl)butane-1,4-diol (diol), cyclizes to 2-(3-pyridyl)tetrahydrofuran (pyridylTHF) and reacts with DNA and hemoglobin to produce adducts.

CYPs是人类和啮齿类动物中NNKα-羟基化反应的主要催化剂。人类CYP代谢NNK的相对效率(从最高催化剂到最低)为:2A13>2B6>2A6>1A2~1A1>2D6~2E1~3A4。这些酶在体内NNK代谢中的实际参与取决于许多因素,包括相对表达水平、给定组织中表达的CYP氧化还原酶的量、组织定位和个体CYP的诱导性,以及人类组织中NNK的浓度。在肝脏CYP中,2B6对NNK的亲和力最高。然而,大多数肝样本中这种酶的水平较低。CYP2A6的含量也相对较低,占总CYP含量的<1%至4%。CYP1A2的水平是CYP2A6的4倍至20倍。因此,尽管其Km略高,Vmax/Km较低,但CYP1A2很可能是人类肝脏中NNKα-羟基化反应的一个重要催化剂,与CYP2A6一样重要。CYP3A4也可能在肝脏NNKα-羟基化反应中发挥作用,因为它的浓度通常是CYP2A6的10至50倍。不能完全排除CYP2A13的存在,这是人类NNK代谢的最佳已知催化剂,存在于肝脏中。然而,相对于CYP2A6,CYP2A13的肝mRNA水平非常低,这表明如果这种酶存在,它也存在于非常低的水平。目前的结果并没有确定肝脏中的任何一个CYP在NNK激活中是关键角色。包括CYP1A2、CYP2A6、CYP2B6和CYP3A4在内的几种酶显然发挥作用。这些CYPs的相对贡献在个体间有所不同,它们的相对丰富度和催化效率表明,几乎从不可能是其中一个占主导地位的催化剂。
CYPs are the major catalysts of NNK alpha-hydroxylation in humans and rodents. ... The relative efficiencies in NNK metabolism by human CYP are (from greatest catalyst to least): 2A13 > 2B6 > 2A6 > 1A2 ~ 1A1 > 2D6 ~ 2E1 ~ 3A4. ... The actual involvement of these enzymes in NNK metabolism in vivo depends on many factors that include relative expression levels, the amount of CYP oxido-reductase expressed in a given tissue, tissue localization and inducibility of individual CYPs, and the concentration of NNK in human tissues. Among hepatic CYPs, 2B6 has the highest affinity for NNK. However, low levels of this enzyme are present in most liver samples. CYP2A6 is also present at relatively low levels, and accounts for < 1% to 4% of the total CYP content. Levels of CYP1A2 are four- to 20-fold higher than those of CYP2A6. Therefore, despite its somewhat higher Km and lower Vmax/Km, CYP1A2 is most probably as important a catalyst of NNK alpha-hydroxylation in human liver as CYP2A6. CYP3A4 may also play a role in hepatic NNK alpha-hydroxylation, since it is often present at concentrations that are 10 to 50 times greater than those of CYP2A6. It is not possible to rule out completely the presence of CYP2A13, the best known human catalyst of NNK metabolism, in the liver. However, the very low hepatic mRNA levels of CYP2A13 relative to CYP2A6 suggest that, if this enzyme is present, it is so at very low levels. Results to date do not identify that any single CYP in the liver is a key player in NNK activation. Several enzymes, including CYP1A2, CYP2A6, CYP2B6 and CYP3A4, clearly play a role. The relative contribution of any one of these CYPs varies among individuals, and their relative abundance and catalytic efficiencies suggest that rarely, if ever, is one of them the dominant catalyst.

曝光:烟草特异性N-亚硝胺,包括4-(甲基亚硝氨基)-1-(3-吡啶基)-1-丁酮(NNK),N'-亚硝基烟碱(NNN),N'-亚硝基阿那巴辛(NAB)和N'-亚硝基阿那塔巴辛(NAT),在烟草和烟草烟雾中广泛存在。它们是由尼古丁和其他烟草生物碱的亚硝化作用形成的,已经在普通烟草(Nicotiana tabacum)和N. rustica品种的绿色烟草叶片中检测到;然而,烟草特异性N-亚硝胺的最大量是在烟草的烘烤和加工过程中形成的,吸烟时还会形成额外的量。烟草特异性N-亚硝胺存在于所有商业性和非商业性准备的烟草产品中,包括香烟、雪茄、比迪斯、烟斗烟草和无烟烟草产品。N-亚硝胺在多种食品和非食品产品中存在,但所有烟草产品中烟草特异性N-亚硝胺的量超过了其他商业产品中其他N-亚硝胺水平的几个数量级。烟草特异性N-亚硝胺的最高水平是在无烟烟草产品中测得的。...接触烟草特异性N-亚硝胺的程度不仅取决于烟草产品或烟雾中这些化合物的水平,还取决于产品的使用方式。对人类的影响:无数据可用。对动物的影响:在多项小鼠研究中,NNK通过不同的给药途径诱导了肺腺瘤。在通过皮下注射的研究中,在大鼠中诱发了肺、鼻腔和肝脏的良性肿瘤和恶性肿瘤。在四项实验中的两项中,诱发了雄性和雌性仓鼠的肺腺瘤、腺癌或腺鳞癌。在另外两项实验中,观察到了腺瘤。在有限的水貂研究中,观察到了涉及前脑的鼻腔肿瘤。在通过饮用水给药的研究和通过口腔擦拭给药的研究中,诱发了雄性大鼠的肺联合良性肿瘤和恶性肿瘤(腺瘤、腺鳞癌和癌)。在饮用水研究中,NNK诱发了胰腺的良性肿瘤和恶性肿瘤。在口腔擦拭研究中,观察到了肝脏和鼻腔的联合良性肿瘤和恶性肿瘤。当NNK被注入雌性大鼠的膀胱时,肝脏和肺肿瘤的发生率显著增加。在两项研究中,通过腹腔注射母鼠使小鼠的后代经胎盘暴露。在两项研究中观察到了雄性后代的肝脏肿瘤,在其中一项研究中还观察到了雌性后代的肝脏肿瘤。在其中一项研究中,还观察到了雄性后代的肺肿瘤。在孕期给予NNK的仓鼠后代研究中,通过气管内注入母鼠诱发了雄性后代的鼻腔腺癌和雄性和雌性后代的肾上腺嗜铬细胞瘤。在第二项研究中,将NNK皮下注射到母鼠中诱发了雄性和雌性后代的呼吸道(鼻腔、喉和气管)肿瘤。当母鼠被皮下注射或通过气管内注入处理时,在第三项研究中,雄性和雌性后代出现了鼻腔和肾上腺肿瘤。NNK-N-氧化物的腹腔给药诱发了雌性小鼠的肺腺瘤。在口腔擦拭研究中,NNK与NNN联合使用增加了大鼠口腔肿瘤的发生率。
Exposure: Tobacco-specific N-nitrosamines, including 4-(methylnitrosamino)-1-(3-pyridyl)-1- butanone (NNK), N'-nitrosonornicotine (NNN), N'-nitrosoanabasine (NAB) and N'-nitrosoanatabine (NAT), occur widely in tobacco and tobacco smoke. They are formed by the nitrosation of nicotine and other tobacco alkaloids and have been detected in green tobacco leaves from Nicotiana tabacum and N. rustica species; however, the largest quantities of tobacco-specific N-nitrosamines are formed during tobacco curing and processing and additional amounts are formed during smoking. Tobacco-specific N-nitrosamines occur in all commercially and non-commercially prepared tobacco products including cigarettes, cigars, bidis, pipe tobacco and smokeless tobacco products. N-Nitrosamines occur in a wide variety of both food and non-food products, but the amounts of tobacco-specific N-nitrosamines in all tobacco products exceed the levels of other N-nitrosamines in other commercial products by several orders of magnitude. The highest levels of tobacco-specific N-nitrosamines are measured in smokeless tobacco products. ... The degree of exposure to tobacco-specific N-nitrosamines depends not only on the levels of these compounds in tobacco products or smoke, but also on the manner in which the products are used. Effects in Humans: No data were available. Effects in Animals: In numerous studies in mice, NNK induced lung adenomas independent of the route of administration. In studies by subcutaneous injection, benign and malignant tumors of the lung, nasal cavity and liver were induced in rats. In two of four experiments in hamsters, lung adenomas and adenocarcinomas or adenosquamous carcinomas were induced in males and females. In the two other experiments, adenomas were observed. Nasal cavity tumours involving the forebrain were observed in a limited study in mink. In a study by administration in the drinking-water and another by oral swabbing, combined benign and malignant lung tumours (adenoma, adenosquamous carcinoma and carcinoma) were induced in male rats. In the drinking-water study, NNK produced benign and malignant pancreatic tumours. In the oral swabbing study, combined benign and malignant tumours of the liver and nasal cavity were observed. Asignificant increase in the incidence of liver and lung tumours was reported in female rats when NNK was instilled into the urinary bladder. In two studies, the offspring of mice were exposed transplacentally by intraperitoneal injection of the dams. Liver tumors were observed in male offspring in both studies and in female offspring in one study. In one of these studies, lung tumors were also observed in male offspring. In studies of the offspring of hamsters given NNK during pregnancy, intratracheal instillation of the dams resulted in adenocarcinomas of the nasal cavity in male offspring and adrenal pheochromocytomas in male and female offspring in one study. In a second study, subcutaneous injection of NNK into dams induced respiratory tract (nasal cavity, larynx and trachea) tumors in male and female offspring. When dams were injected subcutanously or treated by intratracheal instillation, nasal cavity and adrenal gland tumors developed in male and female offspring in a third study. Intraperitoneal administration of NNK-N-oxide induced lung adenomas in female mice. In an oral swabbing study, NNK in combination with NNN increased the incidence of oral tumors in rats.

大量的研究已经检查了NNK的代谢以及NNK及其代谢物4-(甲基硝基亚硝基氨基)-1-(3-吡啶基)-1-丁醇(NNAL)在人类和实验动物中形成DNA加合物的过程;代谢途径和DNA加合物的结构已经被全面表征。NNK和NNAL已经被检测到无烟烟草使用者的唾液中,并且在人类尿液中定量测定了NNAL和NNK的另一种代谢物NNAL-葡萄糖醛酸苷。这些特定于烟草产品暴露的代谢物(例如在吸烟者、无烟烟草使用者和非吸烟者暴露于二手烟)的存在,表明了NNK被人类摄取和代谢,它们的定量测定允许估计吸收的NNK剂量。剂量计算显示,使用烟草产品30年或更长时间的人摄取的NNK总量接近于在大鼠中诱导肿瘤的总量。
Extensive studies have examined the metabolism of NNK and the formation of DNA adducts by NNK and its metabolite 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) in humans and laboratory animals; the metabolic pathways and structures of DNA adducts have been characterized comprehensively. NNK and NNAL have been detected in the saliva of smokeless tobacco users, and NNAL and another metabolite of NNK, NNAL-glucuronide, have been quantified in human urine. The presence of these metabolites, which are specific to exposure to tobacco products (e.g. in smokers, users of smokeless tobacco and nonsmokers exposed to secondhand tobacco smoke), signals human uptake and metabolism of NNK, and their quantification allows an estimation of the dose of NNK absorbed. Dose calculations show that the total amounts of NNK taken up by people who used tobacco products for a period of 30 years or more approximate the total amounts that induce tumors in rats.

无烟烟草使用者对NNK的吸收是通过检测其代谢物4-(甲基硝基亚硝基氨基)-1-(3-吡啶基)-1-丁醇(NNAL)和NNAL-葡萄糖醛酸苷(Gluc)在血浆和尿液中以及尿液中NNAL-N-过氧化物来证明的。在吸烟者中也得到了类似的结果,尽管只在血浆中报告了NNAL。NNAL-N-Gluc在吸烟者的尿液总NNAL-Gluc中占50 +/- 25%,在鼻烟使用者中占24 +/- 12%。Toombak使用者排出了异常高水平的NNAL和NNAL-Gluc(每天0.12到0.14毫克),这表明人类对NNK的摄取量高于任何其他非职业性致癌物。
Absorption of NNK in smokeless tobacco users was demonstrated by the detection of its metabolites, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) and NNAL-glucuronide (Gluc), in plasma and urine and of NNAL-N-oxide in urine. Similar results have been obtained in smokers, although only NNAL has been reported in plasma. NNAL-N-Gluc comprised 50 +/- 25% of total NNAL-Gluc in the urine of smokers and 24 +/- 12% in snuff-dippers. Toombak users excreted exceptionally high levels of NNAL and NNAL-Gluc (0.12 to 0.14 mg per day), which demonstrated a higher uptake of NNK by humans than of any other non-occupational carcinogen.

4-(甲基亚硝基胺)-1-(3-吡啶基)-1-丁醇 (NNAL),但没有检测到 NNAL-葡萄糖苷酸,在吸烟母亲的羊水中被检测到。在吸烟母亲所生的新生儿的尿液中检测到了NNAL和NNAL-葡萄糖苷酸,但在非吸烟母亲所生的新生儿的尿液中没有检测到。这些结果表明NNK在母亲体内转化为NNAL,并且NNAL穿过胎盘屏障,在胎儿发育的后期被吸收并代谢为NNAL-葡萄糖苷酸。
4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), but not NNAL-Gluc, was detected in the amniotic fluid of mothers who smoked. Both NNAL and NNAL-Gluc were detected in the urine of neonates born to mothers who smoked, but not in the urine of newborns of nonsmoking mothers. These results indicate that NNK is converted to NNAL in the mother, and that NNAL crosses the placental barrier and is absorbed and metabolized to NNAL-Gluc in the late stages of fetal development. /NNAL/

吸收、分配和排泄
4-(甲基亚硝基氨基)-1-(3-吡啶基)-1-丁醇(NNAL)和NNAL-葡萄糖醛酸在停止吸烟或使用无烟烟草后,通过尿液排出的速度比根据它们的结构预期要慢。戒烟一周后,尿液中检测到的NNAL加上NNAL-葡萄糖醛酸的基线百分比为34.5%,而与之结构相关的化合物可替宁和尼古丁的相应值分别为1.1%和0.5%。即使在停止6周后,原始水平的NNAL加上NNAL-葡萄糖醛酸仍有7.6%残留。NNAL和NNAL-葡萄糖醛酸的分布半衰期为3到4天,而消除半衰期为40到45天。NNAL的总体清除率估计为61.4 +/- 35.4 mL/min,β相的分布体积估计为3800 +/- 2100 L,这表明大量分布到组织中。在使用无烟烟草后,NNAL的分布半衰期(1.32 +/- 0.85天对3.35 +/- 1.86天)和NNAL-葡萄糖醛酸(1.53 +/- 1.22天对3.89 +/- 2.43天)显著短于吸烟者。终末半衰期没有显著差异。
4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) and NNAL-Gluc are excreted in the urine more slowly than would be expected, based on their structures, after cessation of smoking or smokeless tobacco use. One week after smoking cessation, 34.5% of baseline NNAL plus NNALGluc was detected in urine, whereas the corresponding values for the structurally related compounds cotinine and nicotine were 1.1 and 0.5%, respectively. Even 6 weeks after cessation, 7.6% of the original levels of NNAL plus NNAL-Gluc remained. The distribution half-life of NNAL and NNAL-Gluc was 3 to 4 days, while the elimination half-life was 40 to 45 days. Total body clearance of NNAL was estimated to be 61.4 +/- 35.4 mL/min, and the volume of distribution in the beta-phase was estimated to be 3800 +/- 2100 L, which indicates substantial distribution into tissues. After cessation of smokeless tobacco use, the distribution half-lives of NNAL (1.32 +/- 0.85 versus 3.35 +/- 1.86 days) and NNAL-Gluc (1.53 +/- 1.22 versus 3.89 +/- 2.43 days) were significantly shorter than those in smokers. There were no significant differences in the terminal half-lives. /NNAL/

    Efficient Bioelectronic Actuation of the Natural Catalytic Pathway of Human Metabolic Cytochrome P450s
    摘要:
    Cytochrome (cyt) P450s comprise the enzyme superfamily responsible for human oxidative metabolism of a majority of drugs and xenobiotics. Electronic delivery of electrons to cyt P450s could be used to drive the natural catalytic cycle for fundamental investigations, stereo- and regioselective synthesis, and biosensors. We describe herein 30 nm nanometer-thick films on electrodes featuring excess human cyt P450s and cyt P450 reductase (CPR) microsomes that efficiently mimic the natural catalytic pathway for the first time. Redox potentials, electron-transfer rates, CO-binding, and substrate conversion rates confirmed that electrons are delivered from the electrode to CPR, which transfers them to cyt P450. The film system enabled electrochemical probing of the interaction between cyt P450 and CPR for the first time. Agreement of film voltammetry data with theoretical simulations supports a pathway featuring a key equilibrium redox reaction in the natural catalytic pathway between reduced CPR and cyt P450 occurring within a CPR-cyt P450 complex uniquely poised for substrate conversion.
