description

Chemoselective Fluorescence Studies with Subtilisin and “Thiosubtilisin” The serine hydroxy group in the active site of subtilisin is selectively “phosphylated”3). This is demonstrated using the fluorescent phosphinic fluoride 1. “Thiosubtilisin” does not react with 1 but with the SH-selective and fluorescent vinyl sulfone 2.
