title: A selenide-based approach to photochemical cleavage of peptide and protein backbones at engineered backbone esters.
abstract: A strategy for photochemical cleavage of peptide and protein backbones is described, which is based on a selenide-mediated cleavage of a backbone ester moiety. Studies in model systems establish the viability of the chemistry and suggest the method could be a valuable tool for chemical biology studies of proteins.
