11-beta-Hydroxysteroid Dehydrogenase Type 2

An high-affinity, NAD-dependent 11-beta-hydroxysteroid dehydrogenase that acts undirectionally to catalyze the dehdrogenation of CORTISOL to CORTISONE. It is found predominantly in mineralocorticoid target tissues such as the KIDNEY; COLON; SWEAT GLANDS; and the PLACENTA. Absence of the enzyme leads to a fatal form of childhood hypertension termed, APPARENT MINERALOCORTICOID EXCESS SYNDROME.
