PhysiologyThis is peptidase unit 1 of two peptidase units in the somatic form of angiotensin-converting enzyme. Angiotensin-converting enzyme is an ectoenzyme active in 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.
KnockoutEsther et al. (1997) used targeted homologous recombination to create mice expressing a form of the enzyme that contains only peptidase unit 1. The modified enzyme was catalytically active but entirely secreted from cells. Mice had significant plasma activity but no tissue-bound enzyme. They had low blood pressure, renal vascular thickening, and a urine concentrating defect, and were very similar to completely deficient mice (Esther et al., 1996) except that the renal pathology was less severe.
Pharmaceutical relevanceThe somatic form of angiotensin-converting enzyme containing this peptidase unit together with peptidase unit 2 (M02.004) is a drug target for the control of hypertension.
