RECOMBINANT HUMAN GAMMA-FIBRINOGEN CARBOXYL TERMINAL FRAGMENT (RESIDUES 143-411) BOUND TO CALCIUM AT PH 6.0

Overview

BACKGROUND: Blood coagulation occurs by a cascade of zymogen activation, resulting from minor proteolysis. The final stage of coagulation involves, thrombin generation and limited proteolysis of fibrinogen to give, spontaneously polymerizing fibrin. The resulting fibrin network is, covalently crosslinked by factor XIIIa to yield a stable blood clot., Fibrinogen is a 340 kDa glycoprotein composed of six polypeptide chains, (alphabetagamma)2, held together by 29 disulfide bonds. The globular C, terminus of the gamma chain contains a fibrin-polymerization surface, the, principal factor XIIIa crosslinking site, the platelet receptor, recognition site, and a calcium-binding site. Structural information on, this domain should thus prove helpful in understanding clot formation., RESULTS: The ... [(full description)]
