A [auth L] | PF09396 | Thrombin light chain (Thrombin_light) | Thrombin light chain | 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 cleave ... | Domain |
