STROMELYSIN-1 CATALYTIC DOMAIN WITH HYDROPHOBIC INHIBITOR BOUND, PH 7.0, 32OC, 20 MM CACL2, 15% ACETONITRILE; NMR ENSEMBLE OF 20 STRUCTURES
OverviewOverview
Stromelysin, a representative matrix metalloproteinase and target of drug, development efforts, plays a prominent role in the pathological, proteolysis associated with arthritis and secondarily in that of cancer, metastasis and invasion. To provide a structural template to aid the, development of therapeutic inhibitors, we have determined a, medium-resolution structure of a 20-kDa complex of human stromelysin's, catalytic domain with a hydrophobic peptidic inhibitor using multinuclear, multidimensional NMR spectroscopy. This domain of this zinc hydrolase, contains a mixed beta-sheet comprising one antiparallel strand and four, parallel strands, three helices, and a methionine-containing turn near the, catalytic center. The ensemble of 20 structures was calculated using, on, average, 8 interresidue NOE restraints per residue for the 166-residue, protein fragment complexed with a 4-residue substrate analogue. The mean, RMS deviation (RMSD) to the average structure for backbone heavy atoms is, 0.91 A and for all heavy atoms is 1.42 A. The structure has good, stereochemical properties, including its backbone torsion angles. The, beta-sheet and alpha-helices of the catalytic domains of human stromelysin, (NMR model) and human fibroblast collagenase (X-ray crystallographic model, of Lovejoy B et al., 1994b, Biochemistry 33:8207-8217) superimpose well, having a pairwise RMSD for backbone heavy atoms of 2.28 A when three loop, segments are disregarded. The hydroxamate-substituted inhibitor binds, across the hydrophobic active site of stromelysin in an extended, conformation. The first hydrophobic side chain is deeply buried in the, principal S'1 subsite, the second hydrophobic side chain is located on the, opposite side of the inhibitor backbone in the hydrophobic S'2 surface, subsite, and a third hydrophobic side chain (P'3) lies at the surface.
