INHIBITOR-FREE CATALYTIC FRAGMENT OF HUMAN FIBROBLAST COLLAGENASE, NMR, 30 STRUCTURES
Overview
The high-resolution solution structure of the inhibitor-free catalytic, fragment of human fibroblast collagenase (MMP-1), a protein of 18.7 kDa, which is a member of the matrix metalloproteinase family, has been, determined using three-dimensional heteronuclear NMR spectroscopy. A total, of 30 structures were calculated by means of hybrid distance, geometry-simulated annealing using a total of 3333 experimental NMR, restraints, consisting of 2409 approximate interproton distance, restraints, 84 distance restraints for 42 backbone hydrogen bonds, 426, torsion angle restraints, 125 3JNH alpha restraints, 153 C alpha, restraints, and 136 C beta restraints. The atomic rms distribution about, the mean coordinate positions for the 30 structures for residues 7-137 and, 145-163 is 0.42 +/- 0.04 A ... [(full description)]
