产品介绍： Arginylation is a post-translational modification of an existing peptide chain by addition of an extra arginine. This modification changes primary sequence of protein as well as it's surface change. It is mediated by arginyltransferase ATE1. Arginylation plays an essential role in multiple physiological pathways, for example, in vivo arginylation constitutes a mechanism for degradation of preprocessed proteins or proteolytic fragments that bear Asp and Glu on their N-termini.
