Removal of the mobile region (15 residues) covering the active site of Candida antarctica Lipase A led to a functional enzyme that shows the same stability, activity, and stereoselectivity as the wild‐type enzyme. Interfacial activation, which is a feature of the wild‐type enzyme, was not observed in the truncated variant.
去除覆盖南极假丝酵母脂肪酶A活性位点的移动区域(15个残基),导致了一种功能性酶,其显示出与野生型酶相同的稳定性,活性和立体选择性。在截短的变体中未观察到界面活化,这是野生型酶的特征。
