pubmed:abstractText |
When a crude extract of Pseudomonas testosteroni induced with testosterone was subjected to polyacrylamide gel electrophoresis, six bands that stained for 17 beta-hydroxysteroid dehydrogenase activity was observed. A protein fraction containing the enzyme corresponding to the fastest migrating band and devoid of the other hydroxysteroid dehydrogenase activities has been obtained. This preparation appears to be distinct from the previously isolated 3(17) beta-hydroxysteroid dehydrogenase (EC 1.1.1.51) in its chromatography properties on DEAE-cellulose, substrate and cofactor specificity, immunological properties and heat stability. The preparation appears devoid of 3alpha-, 3beta-, 11beta-, 17alpha-, 20alpha-, and 20beta-hydroxysteroid dehydrogenase activities. The enzyme transfers th 4-pro-S-hydrogen of NADH from estradiol-17beta (1,3,5(10)estratriene-3,17beta-diol) to estrone (3-hydroxy-1,3,5(10)-estratriene-17-one).
