摘要

Asparaginyl endopeptidases (AEPs) are cysteine proteases that control a myriad of cellular functions in plants, including maturation of seed storage proteins and programmed cell death. Recently, several noteworthy AEPs have been discovered that primarily function as transpeptidases rather than hydrolases, to instead catalyse the formation of new peptide bonds. These AEPs appear to have evolved for the cyclisation of a large class of plant defence peptides called cyclotides. Here we describe recent insights into the structural differences between AEPs that preference peptide ligation over hydrolysis. This knowledge is instrumental for the deployment of AEP ligases as biotechnological tools for in vitro applications such as protein labelling and or cyclization, and for plant molecular farming applications.
