The hydrolysis course of PenG catalyzed by penicillin amidase entrapped in the AOT/isooctane reversed micelles was investigated.

通过将青霉素酰化酶包埋于AOT/异辛烷反胶团中，对PenG酶促水解过程进行了研究。

Most of these peptides are amidated at their C-terminals, which is essential for their full activities. The a-amide comes from posttranslational modification that is catalyzed by α-amidase (α-AE or PAM). The amidation reaction is a rate-limiting step in the biosynthesis of regulatory peptides.

大部分活性肽的C-端是酰胺化的，而且α-酰胺基为多肽的完全生物活性所必需；α-酰胺基来自多肽的翻译后加工，由α-酰胺化酶催化完成，是酰胺化多肽生物合成途径中的限述步骤。
