    effect on the stereoselectivity. The increased steric repulsion and the C−H⋅⋅⋅π interaction involving the alkyl side chain of L153 and the phenyl ring of the substrate turned out to be crucial factors connected to the enhanced enzymatic activity. This provided new insight into the role of steric hindrance and non canonical interactions in protein engineering. Furthermore, the recombinant E. coli whole
    为了将短链脱氢酶/还原酶EbSDR8升级为合成抗Prelog手性醇的强大工具,通过重构催化口袋和酶-底物相互作用进行了合理的设计。所得变体显示出对一系列前手性酮的催化效率(k cat / K M;k cat =周转率,K M =米氏常数)显着提高,其中k cat / K M在某些情况下,其值比野生型EbSDR8高15倍以上。更重要的是,没有一个突变对立体选择性产生不利影响。事实证明,增加的空间排斥力和涉及L153的烷基侧链和底物的苯环的CH- H⋅⋅⋅π相互作用是与增强酶促活性有关的关键因素。这为空间位阻和非典型相互作用在蛋白质工程中的作用提供了新的见解。此外,重组大肠杆菌表达EbSDR8变体G94A / S153L的完整细胞成功催化了高浓度的2,2,2-三氟苯乙酮的还原。结果证明了合理设计的有效性以及所设计的变体在有效减少手性酮方面的适用性。

    reductases were stable at elevated substrate loading. Enzymatic characterization revealed that DhCR and CgCR were more thermostable. As much as 330 g COBE in 1 L biphasic reaction mixture was reduced to (S)- and (R)-3-hydroxy-4-chlorobutyrate by DhCR and CgCR (coexpressed with glucose dehydrogenase), with 92.5% and 93.0% yields, >99% ee, and total turnover numbers of 53 800 and 108 000, respectively
    通过重新筛选羰基还原酶工具箱,鉴定出两种健壮的立体互补羰基还原酶(Dh CR和Cg CR)。通过活性和对映选择性测定,对α-氯-1-苯乙酮和4-氯-3-氧代丁酸乙酯(COBE)返回了五种还原酶。三种还原酶在增加的底物负载下稳定。酶促表征显示Dh CR和Cg CR更稳定。Dh CR和Cg将1 L双相反应混合物中多达330 g COBE还原为(S)-和(R)-3-羟基-4-氯丁酸酯CR(与葡萄糖脱氢酶共表达),产率为92.5%和93.0%,ee大于99%,总营业额分别为53 800和108 000。在负载为100 g L -1的情况下,其他六个α-卤代醇不对称还原为光学纯净形式。我们的结果表明这两种立体互补还原酶在合成有价值的药物α-卤代醇中的潜力。

    greener media to obtain higher productivities and selectivities. In the present contribution, an eutectic mixture composed of choline chloride (ChCl): glycerol (1 : 2 mol/mol) has been used as a reaction medium in combination with Tris−SO4 50 mM buffer pH 7.5, applied to the alcohol dehydrogenase (ADH)‐catalyzed reduction of various carbonyl precursors of chiral halohydrins. These alcohols are key
    深共晶溶剂(DESs)在生物技术过程中的应用具有突出的相关性,因为它们可以用作更绿色的介质以获得更高的生产率和选择性。在本文稿中,由胆碱氯化物(ChCl):甘油(1:2 mol / mol)组成的共晶混合物已与Tris-SO 4结合用作反应介质50 mM pH 7.5的缓冲液,用于乙醇脱氢酶(ADH)催化还原手性卤代醇的各种羰基前体。这些醇是生物活性化合物的关键中间体,因此具有工业价值。在存在高达50%v / v的DES的情况下,这些生物转化可实现高达300-400 mM的α-卤代酮底物,从而获得具有优异转化率(通常> 90%)和对映体过量的最终化合物(ee > 99%)。在测试的不同ADH中,有两种立体互补酶(短乳杆菌ADH和红球菌ADH)提供了最好的结果,因此在所有研究的实施例中都可以得到两种醇对映体。选定的生物还原反应可放大至250 mg和1 g,这表明DESs可以作为氧化还原工艺的介质,用于水溶性低的底物。

The computational data obtained for the β-brominated substrates, based on the parameters analysed such as NAC (near attack conformation), distance between Ser-O and carbonyl-C and oxyanion site stabilization were in agreement with the experimental results. On the other hand, the data
