Digging in the database: Four synthetically useful transaminases for which no function was known were studied by evaluating a set of eight amino donors and seven acceptors (see figure). The four enzymes differ substantially in their catalytic properties and substrate preferences. We also used the enzymes in the asymmetric synthesis of a range of chiral amines and observed excellent enantioselectivities

Transaminases (TAs) have recently been established as catalysts for the asymmetric, reductive amination of prochiral ketones. Depending on the ketone substrate and the amine donor (the cosubstrate), equilibrium constants may limit high conversions; thus, methods to overcome this limitation are required. Removal of the co-product from the reaction equilibrium through spontaneous, intramolecular reactions
转氨酶 (TA) 最近已被确定为前手性酮不对称还原胺化的催化剂。根据酮底物和胺供体(共底物),平衡常数可能会限制高转化率;因此,需要克服这种限制的方法。通过自发的分子内反应从反应平衡中去除副产物为这个问题提供了成功的解决方案。因此,这些胺供体被命名为“智能共底物”。在这里,我们比较了各种双功能胺供体,包括作为潜在结构共底物基序的连二胺。在 TA 催化的 1,2-二胺脱氨基作用后,所得 α-氨基酮的自发二聚化和氧化得到杂芳族吡嗪。
Expanding Substrate Specificity of ω-Transaminase by Rational Remodeling of a Large Substrate-Binding Pocket
by severe steric interference in a small active site pocket of ω‐transaminase (ω‐TA). Herein, we demonstrated that structure‐guided remodeling of a largepocket by a single point mutation, instead of excavating the small pocket, afforded desirable alleviation of the steric constraint without deteriorating parental activities toward native substrates. Molecular modeling suggested that the L57 residue
通过生物催化转氨作用生产结构多样的手性胺受到ω-转氨酶(ω-TA)的一个小活性位点空间中的严重空间干扰的挑战。在本文中,我们证明了通过单点突变对大袋进行结构引导的重塑,而不是挖掘小袋,可实现空间约束的理想缓解,而不会降低亲本底物的亲本活动。分子建模表明人O骨菜中ω‐TA的L57残基用作闩锁,迫使笨重的基板与小袋进行空间干涉。通过L57A取代去除闩锁,可以重新定位小袋,并显着提高了对各种芳基烷基胺和烷基胺的活性(例如,α-丙基苄胺的k cat / K M增加1100倍)。这种方法可以提供一种简便的策略来扩大ω-TAs的底物特异性。

Biocatalytic cascade conversion of racemicamines into optically pure ones using enantiocomplementaryω-transaminases (ω-TAs) has been developed by thermodynamic and kinetic control of reaction pathways where 12 competing reactions occur with pyruvate and isopropylamine used as cosubstrates. Thermodynamic control was achieved under reduced pressure for selective removal of a coproduct (i.e., acetone)
通过对反应途径的热力学和动力学控制,利用丙酮酸和异丙胺作为共底物发生了12个竞争反应,通过对反应途径的热力学和动力学控制,已开发出利用对映体互补ω-转氨酶(ω-TAs)将消旋胺生物催化级联转化为光学纯的胺。在减压下实现了热力学控制,以选择性除去副产物(即丙酮),从而消除了六个不良反应。利用ω-TAs底物特异性的工程正交性进行动力学控制,从而可以抑制另外四个反应。两者合计,净反应途径可以针对两个所需的反应(即R-胺的氧化脱氨基和所得酮的还原性胺化成对映体S)。-胺)。这种策略可以对多种手性胺进行一锅除臭,其中ee S > 99%,生成的S-胺产品的反应收率达到85-99%。使用葡萄糖或1-苏氨酸作为廉价的氨基受体前体,可以在活的微生物中成功地进行体外级联反应,这表明合成的代谢途径能够使手性胺脱消脂,这在活生物体中从未观察到。

Difficult-to-access chiralprimaryamines were formed in good to high yield and ee using a rare example of a one-potsynthesis from prochiral ketones (sequentialreductive amination-hydrogenloysis). As a highlight we also demonstrate a one-potreductive amination-hydrogenolysis-reductive amination (five reactions) of ortho-methoxyacetophenone resulting in the chiral diamine 1-(2-methoxyphenyl)ethy
