NMR Structure of Hirudin, 1hic

Template:STRUCTURE 1hic

Hirudin (Hir) is a powerful anticoagulant which is found in the leech salivary glands. It is an inhibitor of thrombin (Thr) which converts fibrinogen to fibrin upon blood clotting. Thrombin is produced upon enzymatic cleavage of prothrombin (ProThr). Hirugen (Hirg) is a dodecapeptide of the C-terminal of Hir (sequence NDGDFEEIPEEYL). The images at the left and at the right correspond to one representative Hirudin, i.e. the NMR Structure of Hirudin (1hic).
