Procollagen peptidase (, procollagen N-terminal peptidase, procollagen aminopeptidase, aminoprocollagen peptidase, aminoterminal procollagen peptidase, procollagen aminoterminal protease, procollagen N-terminal proteinase, type I/II procollagen N-proteinase, type III procollagen) is an endopeptidase involved in the processing of collagen.
Collagen peptidase (, type I/II/III collagen N-proteinase) is an enzyme that participates in the breakdown of collagen by removing amino acids from its N-terminus.
