The molecule is a heterodetic cyclic peptide composed of 65 amino acids joined in sequence and cyclised by three disulfide bridges between cysteine residues 6-14, 16-28 and 22-39. It is a highly specific inhibitor of thrombin and used as an anticoagulant in patients with heparin-induced thrombocytopenia. It has a role as an EC 3.4.21.5 (thrombin) inhibitor and an anticoagulant. It is a polypeptide, a heterodetic cyclic peptide and an organic disulfide.
