Abstract

Reversible as well as stereo- and chemoselective: various proteases such as thermolysin and chymotrypsin catalyze amine acyl exchange in peptides. This acyl exchange can be used to modify amino-functionalized surfaces under physiological reaction conditions and provides an alternative mechanism for posttranslational transpeptidation reactions such as peptide-splicing reactions in the proteasome.Copyright © 2012 WILEY-VCH Verlag GmbH & Co.
