Development of chemical biology tools focusing on peptide/amide bond cleavage reaction

Abstract

Peptides and proteins are involved in almost all biological events. In this review, three chemical biology tools, which were developed for peptide/protein sciences from a viewpoint of peptide/amide bond cleavage, are overviewed. First, study on an artificial amino acid that enables stimulus-responsive functional control of peptides/proteins is briefly described. Two N–S acyl transfer reaction-based tools, one a linker molecule for facile identification of target proteins of bioactive compounds and the other a reagent for selective labeling of proteins of interest, are then discussed.
