Extensive research has validated a pathological role for Angiotensin II in cardiac, renal and vascular diseases. <ref>PMID:17083068</ref> Bradykinin, a small peptide that counterbalance the effects of Angiotensin II by acting as a strong vasodilator upon binding AT2, is degraded by the same ACE-1 enzyme. Since ACE-1 is the primary producer of Angiotensin II and primary degrader of Bradykinins, inhibition of ACE-1 has proven an effective treatment for Hypertension and Congestive Heart Failure. Captopril binds to the ACE-1 binding site of <scene name='Captopril/Ace/1'>Angiotensin-Converting enzyme</scene>, preventing ACE-1 from binding angiotensin. Captopril,<scene name='Captopril/Captopril_binding/1'> binds ACE-1 precisely</scene>, forming electrostatic interactions with His 353, Glu 384, Lys 511, His 513 and Tyr 520, along with zinc cation. <ref>PMID:15236580</ref> | Extensive research has validated a pathological role for Angiotensin II in cardiac, renal and vascular diseases. <ref>PMID:17083068</ref> Bradykinin, a small peptide that counterbalance the effects of Angiotensin II by acting as a strong vasodilator upon binding AT2, is degraded by the same ACE-1 enzyme.
