PhysiologyThis is the more C-terminal peptidase unit of the two peptidase units in the somatic form of angiotensin-converting enzyme, and is the sinngle peptidase unit in the germinal form of the enzyme. Angiotensin-converting enzyme is an ectoenzyme active in the conversion of angiotensin I to hypertensive angiotensin II, and degradation of bradykinin and other bioactive peptides. An insertion/deletion polymorphism is associated with left ventricular hypertrophy.
KnockoutMice in which the germinal form of angiotensin-converting enzyme is entirely secreted have low blood pressure, renal vascular thickening, and a urine concentrating defect (Esther et al., 1997), similarly to mice completely lacking angiotensin-converting enzyme (Esther et al., 1996).
Pharmaceutical relevanceThe somatic form of angiotensin-converting enzyme containing this peptidase unit together with peptidase unit 1 (M02.001) is a drug target for the control of hypertension.
