production of chiral amines: The structures of imine reductases (IREDs) from B. cereus and N. halophila that are S‐selective for the reduction of 2‐methylpyrroline (2MPN) reveal conservation of residues in this IRED subgroup. These structures permit comparison with those of IREDs that are R‐selective for 2MPN reduction, revealing structural differences in the active sites.
不对称产生手性胺的生物催化剂:蜡状芽孢杆菌和嗜盐生芽孢杆菌的亚胺还原酶(IRED)结构具有S选择性,可还原2-甲基吡咯啉(2MPN),显示该IRED亚组中的残基得以保留。这些结构可以与对2MPN还原具有R选择性的IRED进行比较,从而揭示了活性位点的结构差异。
