What does gelatinase hydrolyze?

Proteases that act on proteins break peptide bonds to release amino acids. Gelatin, derived from collagen, is a protein, so gelatinase cleaves its peptide bonds and yields amino acids (often with small peptides as intermediates) as the end products. The other potential products come from different macromolecules—fatty acids from lipids, glucose from carbohydrates, nucleotides from nucleic acids—so they aren’t produced by gelatinase activity.
