WebDec 13, 2013 · Trypsin, Lys-C, and Lys-N are the most broadly used enzymes in proteomics. Here, on the basis of large-scale peptide mass spectrometry (MS) data sets, an approach … WebIt represents the absence of any enzyme and should not be confused with "None". "semiTrypsin" means that Mascot will search for peptides that show tryptic specificity (KR not P) at one terminus, but where the other terminus may be a non-tryptic cleavage. This is a half-way house between choosing "Trypsin" and "None".
