both required a peptide with a minimum of six amino acid residues to demonstrate significant gelatinolytic activity and were able to cleave uncharged molecules more rapidly than charged molecules . the repeating gly-x-y-gly sequence of collagen is not an absolute requirement for either enzyme since both digested acpro-leu-gly-ile-leu-ala-ala-oc2h5 at 70 % of the rate of the best substrate peptide , acpro-leu-gly-leu-leu-gly-oc2h5 .
