CRYSTAL STRUCTURE OF THE CATALYTIC DOMAIN OF HUMAN FIBROBLAST STROMELYSIN-1 INHIBITED WITH THIADIAZOLE INHIBITOR PNU-141803
Overview
The binding of two 5-substituted-1,3,4-thiadiazole-2-thione inhibitors to, the matrix metalloproteinase stromelysin (MMP-3) have been characterized, by protein crystallography. Both inhibitors coordinate to the catalytic, zinc cation via an exocyclic sulfur and lay in an unusual position across, the unprimed (P1-P3) side of the proteinase active site. Nitrogen atoms in, the thiadiazole moiety make specific hydrogen bond interactions with, enzyme structural elements that are conserved across all enzymes in the, matrix metalloproteinase class. Strong hydrophobic interactions between, the inhibitors and the side chain of tyrosine-155 appear to be responsible, for the very high selectivity of these inhibitors for stromelysin. In, these enzyme/inhibitor complexes, the S1' enzyme subsite is ... [(full description)]
