General description
The angiotensin-converting enzyme (ACE) is a dipeptidyl-carboxypeptidase which exists in somatic and testicular isoforms with zinc binding motif HEXXH in their active site. ACE regulates blood pressure through renin-angiotensin system. ACE elevates blood pressure by converting angiotensin I to a key vasoconstrictor angiotensin II and inhibiting a potent vasodilator bradykinin. Inhibition of ACE is a targeted therapeutic strategy for high blood pressure. Several ACE synthetic inhibitory peptides available for clinical use include captopril, enalapril and lisinopril. Currently, developing inhibitory peptides from natural food sources, or phenolic compounds from plant sources to inhibit ACE is underway. ACE plays a critical role in fertilization by releasing the proteins anchored to glycosylphosphatidylinositol (GPI) in sperm membrane.
Application
Angiotensin converting enzyme from rabbit lung has been used:
- for measuring inhibitory effect of egg white protein hydrolysates on ACE activity by high performance liquid chromatography (HPLC)
- to measure the ACE inhibition by litchi pericarp and cooked chicken breast using hippuryl-L-histidyl-L-leucine (HHL) as substrate by reverse phase-HPLC (RP-HPLC)3 and HPLC respectively
- in releasing GPI anchored protein in vitro in few cell lines like HeLa, HEK293 and in vivo in mice sperm.
Biochem/physiol Actions
Removes C-terminal dipeptides from susceptible substrates, e.g., angiotensin I and bradykinin.
Analysis Note
May contain traces of sodium chloride.
Other Notes
One unit will produce 1.0 μmole of hippuric acid from Hippuryl-His-Leu per min in 50 mM HEPES and 300 mM NaCl at pH 8.3 at 37 °C.

What is the medical significance of Angiotensin Converting Enzyme (ACE), Product A6778?
1 answer-
Angiotensin-converting enzyme (ACE) produces angiotensin II, a substance that affects the cardiovascular system in numerous ways, including narrowing of blood vessels. This narrowing can cause high blood pressure and cause the heart to work harder. ACE inhibitors treat a variety of conditions, such as high blood pressure, scleroderma and migraines. (Mayo Clinic)

Are there any other known inhibitors of rabbit lung Angiotensin Converting Enzyme (ACE), Product A6778?
1 answer-
Idrapril, the prototype of a new class of angiotensin converting enzyme (ACE) inhibitors, competitively inhibits, with nanomolar apparent Ki, the hydrolysis of hippuryl-glycyl-glycine by rabbit lung ACE. Kinetic Ki and kon and koff values were 470 pM, 3.0±1.5×106 M-1sec-1 and 1.4±0.3×10-3 sec-1, respectively. Reference: Biochemical Pharmacology, 45(6), 1358-1362 (1993).
