Abstract

An improved protocol for copper-catalyzed triazole formation on the bacterial cell surface is described. Addition of highly pure CuBr to cells treated with azidohomoalanine (2) leads to ca. 10-fold more extensive cell surface labeling than previously observed. This highly active catalyst allows detection of the methionine analogues azidoalanine (1), azidonorvaline (3), and azidonorleucine (4) in cell surface proteins. Azidoalanine was previously believed to be silent with regard to the cellular protein synthesis machinery.
