Abstract
Trypsin reacts with S-methylisothiourea for 1 to 2 h and the number of primary amine sites at which covalent labeling occurs is determined by mass spectrometry. By digesting the amidinated trypsin and mass analyzing the proteolytic peptides the sites of reaction are determined. The addition of cytochrome c to a solution of amidinated trypsin enables the proteolytic activity and autolytic properties of the enzyme to be studied.
