生物活性肽或蛋白质如激素、肽类神经介质等通常是由大的蛋白质前体经酶的加工后产生的。人们把由大的蛋白质前体形成活性分子的过程称之为翻译后加工(post-transla-tional processing)。这种加工过程普遍存在于所有生物体,包括细菌、病毒中,它参 Bioactive peptides or proteins such as hormones, peptide neurotransmitters and the like are usually produced by enzymatic processing of large protein precursors. The process of forming active molecules from large protein precursors is called post-transla-tional processing. This process is widespread in all organisms, including bacteria, viruses, and its reference
