Thrombin (beta, gamma) PRODUCT INQUIRY Proteolyzed Forms of α-Thrombin The degradation pattern of human α-thrombin to less active forms is illustrated above. β-thrombin is generated by cleavage of the intact B-chain at the Arg106-Tyr107 bond to yield the B1 and B2 fragments. γ-thrombin is generated by further cleavage of the β-thrombin B2-chain at the Lys190-Gly191 bond to yield the B4 and B5 fragments. Although not illustrated, the B3 fragment is a potential intermediate that is derived by cleavage of the intact B-chain at the Lys190-Gly191 bond, resulting in a product that is often referred to as β'-thrombin. (The amino acid numbering used here begins at the NH2-terminal end of the A-chain and continues through the B-chain).
