Proteases for Mass Spectrometry

Trypsin, the most widely used protease in mass spectrometry analysis, utilizes its high specificity to cleave proteins, resulting in peptides with a strong C-terminal charge. Trypsin is a serine protease that specifically cleaves at the carboxylic side of lysine and arginine residues. Lysine residues in the porcine trypsin have been modified by reductive methylation, yielding a highly active and stable molecule that is extremely resistant to autolytic digestion. The specificity of the purified trypsin is further improved by TPCK treatment, which inactivates chymotrypsin.

When working with tightly folded proteins, the...
