Proteomics Using Protease Alternatives to Trypsin Benefits from Sequential Digestion with Trypsin

Therese Dau, Giulia Bartolomucci, Juri Rappsilber Analytical Chemistry, 2020 Trypsin is the most used enzyme in proteomics. Nevertheless, proteases with complementary cleavage specificity have been applied in special circumstances. In this work, we analyzed the characteristics of five protease alternatives to trypsin for protein identification and sequence coverage when applied to S. pombe whole cell lysates.
