  摘要：

  基于相应的α-酮酸通过由工程脱氢酶和辅因子回收装置组成的重组全细胞系统的还原胺化反应，已开发出一种实用，有效的芳香族d-氨基酸生物催化合成方法。结果表明，在制备规模上，该反应在多种底物上均具有出色的对映选择性（≥98％）和良好的收率。另外，解析了变体酶的结构以使观察到的反应速率合理化。工程化的全细胞催化剂还通过与对映体互补脱氨酶结合使用，来介导外消旋混合物和更便宜的l-氨基酸产生的d-苯丙氨酸衍生物。

  isomerization of various racemic α- and β-arylalanines catalysed by phenylalanine 2,3-aminomutase from Pantoea agglomerans (PaPAM) was investigated. Both α- and β-arylalanines were accepted as substrates when the aryl moiety was relatively small, like phenyl, 2-, 3-, 4-fluorophenyl or thiophen-2-yl. While 2-substituted α-phenylalanines bearing bulky electron withdrawing substituents did not react, the corresponding
