Evaluation of an esterase annotated as 26D isolated from a marine metagenomic library is described. Esterase 26D was found to have a unique substrate scope, including synthetic transformations which could not be readily effected in a synthetically useful manner using commercially available enzymes. Esterase 26D was more selective towards substrates which had larger, more sterically demanding substituents
描述了评估从海洋宏基因组库中分离为26D的酯酶的方法。发现酯酶26D具有独特的底物范围,包括使用市售酶不易以合成有用的方式实现的合成转化。酯酶26D是更具选择性的朝向具有较大的,更空间要求的取代基的底物(即,异-丙基或叔-丁基基团)上的β碳,这是相对于其中显示的偏好基板与空间位先前测试的市售的酶β-碳原子上的取代基(例如甲基)要求较低。
