Chains Pfam Accession Pfam Identifier Pfam Description Type Source
H PF00089 Trypsin Trypsin Domain PFAM PF00089
L PF09396 Thrombin_light Thrombin light chain Domain 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. PFAM PF09396
