CRYSTAL STRUCTURES OF THROMBIN WITH THIAZOLE-CONTAINING INHIBITORS: PROBES OF THE S1' BINDING SITE
|
OverviewOverview
Structures of the blood clotting enzyme thrombin complexed with hirugen, and two active site inhibitors, RWJ-50353, 10080(N-methyl-D-phenylalanyl-N-[5-[(aminoiminomethyl)amino]-1-, [[(2-benzothiazolyl)carbonyl]butyl]-L-prolinamide trifluoroacetate, hydrate) and RWJ-50215 (N-[4-(aminoiminomethyl)amino-1-[2-, (thiazol-2-ylcarbonylethyl)piperidin-, 1-ylcarbonyl]butyl]-5-(dimethylamino)naphthalenesulfonamide, trifluoroacetate hydrate), were determined by x-ray crystallography. The, refinements converged at R values of 0.158 in the 7.0-2.3-A range for, RWJ-50353 and 0.155 in the 7.0-1.8-A range for RWJ-50215. Interactions, between the protein and the thiazole rings of the two inhibitors provide, new valuable information about the S1' binding site of thrombin. The, RWJ-50353 inhibitor consists ...
