概述

Thrombin is a "trypsin-like" serine protease protein.Prothrombin(coagulation factor II)is proteolytically cleaved to form thrombin in the coagulation cascade,which ultimately results in the stemming of blood loss.As a result of cleaving,thrombin has two chains:a light chain(A chain,MW~6kDa)and a heavy chain(B chain,MW~31 kDa).These two chains are joined by one disulfide bond.Functions of thrombin are that it converts soluble fibrinogen into insoluble strands of fibrin,as well as catalyzes many other coagulation-related reactions.Thrombin also contains g-carboxyglutamyl residues.These modified glutamyl residues are the result of carboxylation by a microsomal enzyme,vitamin Kdependent carboxylase.g-Carboxyglutamyl residues are necessary for the Ca2+-dependent interaction with a negatively charged phospholipid surface,which is essential for the conversion of prothrombin to thrombin.
