Hydroxysteroid dehydrogenases in the kidney of white-breasted water hen, Amaurornis phoenicurus chinensis (Boddaert).
Histochemical localization of delta5-3beta-hydroxysteroid dehydrogenase (delta5-3beta-HSDH), 17beta-hydroxysteroid dehydrogenase (17beta-HSDH), 11beta-hydroxysteroid dehydrogenase (11beta-HSDH) and glucose-6-phosphate dehydrogenase (G-6-PDH) have been studied in the kidney of white-breasted water hen, Amaurornis phoenicurus chinensis. All these enzyme activities occurred in the proximal and distal convoluted and collecting tubules, however, the intensity of these enzyme activities was more in the proximal convoluted tubules. It is suggested that these enzymes might have a role in converting certain hydroxysteroids to ketosteroids during steroid excretion.
