代谢
乙醇胺可以被多种系统发育不同的细菌用作碳和氮的来源。乙醇胺-裂合酶是分解乙醇胺为乙醛的酶,由串联基因eutBC编码。尽管对肠炎沙门氏菌鼠伤寒血清型对乙醇胺利用进行了广泛的研究,但对于EutBC的结构和催化机制、乙醇胺利用的进化起源,以及乙醇胺本身与乙醇胺-裂合酶辅因子腺苷钴胺素之间的调控联系,还有很多需要了解。我们通过对乙醇胺-裂合酶的序列、结构、基因组环境和系统发育的计算分析来回答这些问题,并评估了近期提出细菌食物中毒与二醇利用途径相关性的数据挖掘研究。我们发现EutBC的进化包括招募一个TIM桶结构域和一个Rossmann折叠结构域,并将它们分别与N末端的α-螺旋结构域融合,形成了EutB和EutC。这种融合之后,在厚壁菌门中招募并偶尔丢失辅助乙醇胺利用基因,并通过几次平转移,尤其是从厚壁菌门干细胞到肠杆菌科,以及从α-变形菌门到放线菌门。我们鉴定了一个可能代表EutR结合位点的保守DNA基序,这个基序在几种肠杆菌科的乙醇胺和胺素操纵子中共享,这表明这些物种中存在一种将无酶蛋白和辅因子生物合成联系起来的机制。最后,我们发现食物中毒表型与代谢体的结构成分的联系比与乙醇胺利用基因或与其同源的丙二醇利用基因本身更为紧密。
Ethanolamine can be used as a source of carbon and nitrogen by phylogenetically diverse bacteria. Ethanolamine-ammonia lyase, the enzyme that breaks ethanolamine into acetaldehyde and ammonia, is encoded by the gene tandem eutBC. Despite extensive studies of ethanolamine utilization in Salmonella enterica serovar Typhimurium, much remains to be learned about EutBC structure and catalytic mechanism, about the evolutionary origin of ethanolamine utilization, and about regulatory links between the metabolism of ethanolamine itself and the ethanolamine-ammonia lyase cofactor adenosylcobalamin. We used computational analysis of sequences, structures, genome contexts, and phylogenies of ethanolamine-ammonia lyases to address these questions and to evaluate recent data-mining studies that have suggested an association between bacterial food poisoning and the diol utilization pathways. We found that EutBC evolution included recruitment of a TIM barrel and a Rossmann fold domain and their fusion to N-terminal alpha-helical domains to give EutB and EutC, respectively. This fusion was followed by recruitment and occasional loss of auxiliary ethanolamine utilization genes in Firmicutes and by several horizontal transfers, most notably from the firmicute stem to the Enterobacteriaceae and from Alphaproteobacteria to Actinobacteria. We identified a conserved DNA motif that likely represents the EutR-binding site and is shared by the ethanolamine and cobalamin operons in several enterobacterial species, suggesting a mechanism for coupling the biosyntheses of apoenzyme and cofactor in these species. Finally, we found that the food poisoning phenotype is associated with the structural components of metabolosome more strongly than with ethanolamine utilization genes or with paralogous propanediol utilization genes per se.

代谢
使用裸鼠、移植了人皮的裸鼠以及离体的猪皮进行了局部应用放射性碳14标记的乙醇胺的分布和代谢研究。在移植了人皮的裸鼠、小鼠皮肤和猪皮中,乙醇胺是唯一检测到的放射性磷脂碱。穿透人皮移植或小鼠皮肤的乙醇胺在动物体内被广泛代谢。肝脏是乙醇胺代谢的主要场所,含有超过24%的施用放射性剂量。肾脏、肺、大脑和心脏分别含有2.53%、0.55%、0.27%和0.15%的剂量。肝脏、人皮移植和小鼠皮肤的蛋白质也具有很高的放射性。超过18%的局部放射性剂量氧化为14CO2,24小时内4.6%通过尿液排出。尿素、甘酸、丝氨酸胆碱尿酸乙醇胺的尿液代谢产物。
The distribution and metabolism of topical (14)C ethanolamine was studied in vivo, using athymic nude mice, human skin grafted onto athymic nude mice, and in vitro, using excised pig skin. Ethanolamine was the only radioactive phospholipid base detected in the human skin grafts, in the mouse skin, and in the pig skin. Ethanolamine that penetrated human skin grafts or mouse skin was extensively metabolized in the animal. The liver is a major site for metabolism of ethanolamine, containing over 24% of the applied radioactive dose. The kidneys, lungs, brain, and the heart contained 2.53, 0.55, 0.27, and 0.15% of the dose, respectively. Hepatic, human skin graft, and mouse skin proteins were also highly radioactive. Over 18% of the topical radioactive dose oxidized to (14)CO2 and 4.6% was excreted in the urine over 24 hr. Urea, glycine, serine, choline, and uric acid were the urinary metabolites of ethanolamine.

毒理性
  • 毒性总结
识别和使用:2-乙醇是一种无色、粘稠的液体或固体(在51°F以下)。目前在美国没有注册为农药使用,但批准的农药用途可能会定期更改,因此必须咨询联邦、州和地方当局以获取当前批准的用途。基和羟基的双重功能团使其在切削液中以及在生产表面活性剂、肥皂、盐、腐蚀控制抑制剂和药物及杂项应用中作为中间体非常有用。2-乙醇和其他胺类似乎是有潜力的成分,可以用于外用制剂,用于消毒和保护皮肤免受化学战剂的影响。作为一种药物辅助剂,它被用作脂肪和油的溶剂,并且与脂肪酸结合形成肥皂,用于各种乳液配方,如乳液和面霜。它用于力压裂。人类暴露和毒性:5.9%的浓度对人类皮肤有刺激性。与人类中枢神经系统抑制相关的症状包括血压升高、多尿、流涎和瞳孔扩张。大量服用会导致镇静、昏迷,随后血压下降和心脏衰竭导致死亡。据报道,人类吸入2-乙醇会引起即时过敏反应,如呼吸困难、哮喘和急性肝损伤和慢性肝炎的临床症状。动物研究:未稀释的液体涂抹在兔子的皮肤上会引起红肿。在狗体内通过静脉注射2-乙醇会产生血压升高、多尿、流涎和瞳孔扩张。在大鼠、小鼠、兔子和豚鼠暴露于高浓度(高达1250 ppm)的蒸汽或雾中时,会发展出肺、肝和肾的病变。在为期90天的2-乙醇大鼠亚急性口服毒性研究中,最大每日剂量为0.32 g/kg没有效果;0.64 g/kg/天会导致肝脏或肾脏重量改变;在1.28 g/kg时会导致死亡。它被认为是一种肝毒素。在狗体内给予高达22 mg/kg/d的2-乙醇长达2年,没有观察到与治疗相关的影响。在兔子的发育研究中,在两个较高剂量平(25、75 mg/kg体重)观察到母体毒性,表现为皮肤刺激,在最高剂量平上还会减少体重增加。治疗对任何胎儿变异或畸形的发病率或畸形胎儿数量没有影响。2-乙醇在Ames沙门氏菌(Salmonella typhimurium)测试中,无论是否使用S9代谢活化,使用TA 1535、TA 1537、TA 1538、TA 98和TA 100,都已被证明不具有诱变性;在Escherichia coli测试、酿酒酵母基因转化测试和鼠肝染色体测试中也为阴性。生态毒性研究:使用斑马鱼鱼苗(Brachydanio rerio)和单细胞藻类Isochrysis galbana(一种鞭毛虫)和Chaetoceros gracilis(一种藻)进行了生毒性测试。藻类的细胞分裂抑制、叶绿素含量和(14)CO2吸收是敏感的终点。2-乙醇对斑马鱼鱼苗的LC50高于5,000 mg/L。
IDENTIFICATION AND USE: 2-Aminoethanol is a colorless, viscous liquid or solid (below 51 °F). It is not registered for current pesticide use in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. The dual function groups, amino and hydroxyl, make it useful in cutting fluids and as intermediates in the production of surfactants, soaps, salts, corrosion control inhibitors, and in pharmaceutical and miscellaneous applications. 2-Aminoethanol and other amines appear to be potentially useful components of topical formulations used to decontaminate and protect the skin against chemical warfare agents. As a pharmaceutical adjuvant, it is used as a solvent for fats and oils, and in combination with fatty acids forms soaps in the formulations of various types of emulsion such as lotions and creams. It is used in hydraulic fracturing. HUMAN EXPOSURE AND TOXICITY: A concentration of 5.9% is irritating to human skin. Symptoms associated with CNS depression in humans include increased blood pressure, diuresis, salivation, and pupillary dilation. Large doses produce sedation, coma, and death following depression of blood pressure and cardiac collapse. 2-Aminoethanol inhalation by humans has been reported to cause immediate allergic responses of dyspnea and asthma and clinical symptoms of acute liver damage and chronic hepatitis. ANIMAL STUDIES: Undiluted liquid causes redness and swelling when applied to the skin of the rabbit. Administration of 2-aminoethanol by the intravenous route in dogs produced increased blood pressure, diuresis, salivation, and pupillary dilation. Rats, mice, rabbits, and guinea pigs exposed to vapor or mist at high concentrations (up to 1250 ppm) developed pulmonary, hepatic, and renal lesions. In a 90-day subacute oral toxicity study of 2-aminoethanol in rats that a maximum daily dose of 0.32 g/kg resulted in no effect; 0.64 g/kg/day resulted in altered liver or kidney wt; and at 1.28 g/kg death occurred. It is considered to be liver toxin. No treatment-related effects were noted in dogs administered as much as 22 mg/kg/d of 2-aminoethanol for 2 yr. In developmental studies in rabbits maternal toxicity was seen at the two higher dose levels (25, 75 mg/kg body weight) as skin irritation and at the highest dose level as reduced weight gain. There was no treatment related effect on the incidence of any fetal variation or malformation or on the number of malformed fetuses. 2-Aminoethanol has been demonstrated to be non-mutagenic in the Ames Salmonella typhimurium assay, with and without S9 metabolic activation, using TA 1535, TA 1537, TA 1538, TA 98, and TA 100; and also negative in the Escherichia coli assay, Saccharomyces gene conversion assay, and rat liver chromosome assay. ECOTOXICITY STUDIES: Aquatic toxicity tests were conducted using zebra fish fry (Brachydanio rerio) and the unicellular algae Isochrysis galbana (a flagellate) and Chaetoceros gracilis (a diatom). Inhibition of cell division, chlorophyll content, and (14)CO2 uptake in the algae were sensitive end points. 2-Aminoethanol had an LC50 /in the zebra fish fry/ higher than 5,000 mg/L.
