Angiotensin converting Enzyme (ACE), denatured. The epitope recognized is localized on the NH2-terminal side of the molecule. Topographically the degree of expression correlates with the proportion of smooth muscle cells and elastic fibres of the vessel wall. ACE is predominantely expressed by small muscular arteries and by arterioles, whereas small and large veins do not usually express ACE. However, no ACE could be detected in the endothelial cells of kidney. Constitutively ACE is expressed on endothelial cells in different diseases like hypertension, myocardial infarction, sarcoidosis, diabetes.

Hintergrund
ACE converts angiotensin I to angiotensin II by release of the terminal His-Leu, this results in an increase of the vasoconstrictor activity of angiotensin. Also able to inactivate bradykinin, a potent vasodilatator. ACE exists in two forms, a 170KD somatic form and a 90KD germinal form. The somatic form is expressed by endothelial cells (especially those of lung capillaries and arterioles), epithelial cells (especially in proximal renal tubules and small intestine), by some neuronal cells and variably by some macrophages and T lymphocytes. The germinal form is expressed by spermatozoa.Synonyms: Angiotensin-converting enzyme, DCP, DCP1, Dipeptidyl carboxypeptidase I
