Description
H-Pro-Gly-Pro-OH (PGP) is a tripeptide generated from the breakdown of extracellular matrix collagen and is specifically chemotactic for neutrophils in vitro and in vivo. Ac-PGP generated by N-terminal acetylation of PGP can enhance this chemotactic potential. PGP was identified as physiological substrate for the aminopeptidase activity of leukotriene A4 hydrolase. PGP is a biomarker for chronic obstructive pulmonary disease (COPD).
