Purification of 3α‐hydroxysteroid and 3β‐hydroxysteroid dehydrogenases from human liver cytosol
Hajime Takikawa, Makoto Fujiyoshi, Kou Nishikawa, Masami Yamanaka – 1 August 1992 – We previously reported that the human Y′ bile acid binder, which has higher bile acid binding affinities than rat Y′ binders (3α‐hydroxysteroid dehydrogenases), has dihydrodiol dehydrogenase activity and is different from 3α‐hydroxysteroid dehydrogenases. In this study, 3α‐hydroxysteroid dehydrogenases and 3β‐hydroxysteroid dehydrogenase were purified from human liver, and bile acid binding affinities and enzyme kinetics of the 3α‐hydroxysteroid dehydrogenases were studied.
