摘要：

Four highly specific hydroxysteroid dehydrogenases have been purified from bacteria. Substrate specificity studies reveal them to be (a) ring A/B trans 3β-hydroxysteroid dehydrogenase, (b) 3α-hydroxysteroid dehydrogenase unable to oxidize 3α-hydroxysteroids ring A/B cis with an 11-keto group, (c) ring A/B trans 3α-hydroxysteroid dehydrogenase, and (d) an axial 3-hydroxysteroid dehydrogenase. The possible application of these enzymes for the quantitative determination of specific steroid groups is presented. © 1969, American Chemical Society. All rights reserved.
