Peptidase specificity

Specificity is only shown where there are at least ten known substrates for a peptidase. The brighter the shade of green the greater the preference at each position. Specificity is shown in terms of the following amino acid groups: aliphatic (Ile, Leu, Val), aromatic (Phe, Trp, Tyr), acidic (Asp, Glu), basic (Arg, His, Lys), small (Ala, Cys, Gly, Ser) and other (Asn, Gln, Met, Pro, Thr). Positions where no amino acid is possible (for example P4-P2 for an aminopeptidase or P2'-P4' for a carboxypeptidase) are shown with a grey background.
