CRYSTAL STRUCTURE OF FRAGMENT DOUBLE-D FROM HUMAN FIBRIN WITH TWO DIFFERENT BOUND LIGANDS
Contents |
Overview
Factor XIII-cross-linked fragment D (double-D) from human fibrin was, crystallized in the presence of two different peptide ligands and the, X-ray structure determined at 2.3 A. The peptide Gly-Pro-Arg-Pro-amide, which is an analogue of the knob exposed by the thrombin-catalyzed removal, of fibrinopeptide A, was found to reside in the gamma-chain holes, and the, peptide Gly-His-Arg-Pro-amide, which corresponds to the beta-chain knob, was found in the homologous beta-chain holes. The structure shows for the, first time that the beta-chain knob does indeed bind to a homologous hole, on the beta-chain. The gamma- and beta-chain holes are structurally very, similar, and it is remarkable they are able to distinguish between these, two peptides that differ by a single amino acid. Additionally, we have, found that the beta-chain domain, like its gamma-chain counterpart, binds, calcium.
