The X-ray crystal structure of a 19 kDa active fragment of human fibroblast collagenase has been determined by the multiple isomorphous replacement method and refined at 1.56 A resolution to an R-factor of 17.4%. The current structure includes a bound hydroxamate inhibitor, 88 waters and three metal atoms (two zincs and a calcium). The overall topology of(More)
Hypersensitivity reactions to the drug abacavir, used to treat HIV/AIDS patients, is associated with possession of HLA-B*57:01. We have carefully assessed two commercially available HLA-B57/B58 murine monoclonal antibodies [0196HA and BIH0243 (One Lambda Inc.)] in a simple flow cytometry-based assay. The evaluation involved tests on 228 reference and random(More)
September 2004 brought beautiful fall weather and 200 conservationists, land managers, and old growth enthusiasts to the shores of Lake Winnipesauke in Moultonborough NH for the 6 th Eastern Old Growth Conference. The conference was dedicated to furthering the scientific understanding and conservation of old growth forests in the eastern US and Canada and(More)
In this study, structure-based drug design of matrix metalloproteinase inhibitors [human fibroblast collagenase (HFC), human fibroblast stromelysin (HFS), and human neutrophil collagenase (HNC)] was utilized in the development of potent hydroxamates which contain novel, heteroatom-based modifications of the P1' group. A series containing a P1' butyramide(More)
We report here the backbone 1HN, 15N, 13C alpha, 13CO, and 1H alpha NMR assignments for the catalytic domain of human fibroblast collagenase (HFC). Three independent assignment pathways (matching 1H, 13C alpha, and 13CO resonances) were used to establish sequential connections. The connections using 13C alpha resonances were obtained from HNCOCA and HNCA(More)
