Abstract
Measurement of the stabilities of DD-carboxypeptidase activity and the penicillin-binding activity of proteins 5 and 5a in membranes isolated from vegetative cells and stage-V forespores suggests that the unique sporulation-specific protein 5a may be a penicillin-sensitive DD-carboxypeptidase.
摘要
对从营养细胞和V期前芽孢分离出的膜中蛋白质5和5a的DD-羧肽酶活性及青霉素结合活性的稳定性进行测量，结果表明，独特的芽孢形成特异性蛋白质5a可能是一种对青霉素敏感的DD-羧肽酶。
