Angiotensin converting enzyme from sheep mammary, lingual and other tissues.
Occurrence of angiotensin converting enzyme (ACE) in mammary gland and tongue taste epithelium was demonstrated for the first time. Six times higher ACE activity in lactating mammary gland, than non-lactating mammary gland, suggested pregnancy and lactation hormonal dependent expression of ACE in female mammals. ACE activity was highest in choroid plexus, less in spinal cord and moderate in cerebrum, medulla, cerebellum and pons. Distribution of ACE in different regions of skin, kidney and among other tissues was different. Presence of ACE in adrenal glands, pancreas, bone marrow and thyroid gland indicated functions other than blood pressure homeostasis for this enzyme.
