Merck, A2580-.5UN, Angiotensin Converting Enzyme from porcine kidney

General description
Angiotensin converting enzyme (ACE) is encoded by the gene, mRNA-decapping enzyme subunit 1 (DCP1). It is a zinc metalloprotease, which belongs to the M2 family.
ACE is a monomer with molecular weight of ~170 kDa
pH range for activity: 7-8.5
Temperature optimum: 37 °C
Zinc is required for activity
Inhibitors: captopril, enalaprilat, lisinopril etc. (1-10 μM)
Application
Angiotensin converting enzyme from porcine kidney has been used in in vitro angiotensin-converting enzyme (ACE) inhibition assay.
Biochem/physiol Actions
Angiotensin converting enzyme (ACE) catalyzes the conversion of angiotensin I to angiotensin II, which regulates the fluid-electrolyte balance and systemic blood pressure. ACE inhibits the vasodilator, bradykinin. ACE inhibitors are used to treat high blood pressure.
Removes C-terminal dipeptides from susceptible substrates, e.g., angiotensin I and bradykinin.
Physical form
Lyophilized powder containing Tris buffer salts.
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.
