PROCARBOXYPEPTIDASE TERNARY COMPLEX

OverviewOverview
Matrix metalloproteinases (MMP) are zinc endopeptidases involved in tissue, remodelling. They have been implicated in a series of pathologies, including cancer, arthritis, joint destruction and Alzheimer's disease., Human neutrophil collagenase represents one of the three interstitial, collagenases that cleave triple-helical collagen of type I, II and III., Its catalytic domain (residues Phe79-Gly242) has been heterologously, expressed in Escherichia coli and crystallized as a non-covalent complex, with the hydroxamate inhibitor BB-1909, which has distinct selectivity, against different MMP, in a crystal form. The crystal structure, refined, to 0.18-nm resolution, shows that BB-1909 is a right-hand-side inhibitor, that binds to the S1'-S3' subsites and coordinates to the catalytic Zn2+, in a bidentate manner via the hydroxyl and carbonyl oxygen atoms of the, hydroxamate group in a similar manner to batimastat. The, collagenase/BB-1909 complex is described in detail and compared with the, collagenase/batimastat complex. These studies provide information on MMP, specificity and thus may assist the development of more-selective MMP, inhibitors.
