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".
