. "Thrombin is an enzyme that cleaves bonds after Arg and Lys,converts fibrinogen to fibrin and activates factors V, VII, VIII. Prothrombin is activated on the surface of a phospholipid membrane where factor Xa removes the activation peptide and cleaves the remaining part into light and heavy chains. This domain corresponds to the light chain of thrombin. " . "Thrombin_light" . "Thrombin light chain" . "Mistry J" . "Domain" . . . . . . . . . . . . . . . .
