additional information	identification of a putative 3beta-hydroxy-steroid dehydrogenase/DELTA5-DELTA4 isomerase pathway with the ability to handle both dehydroepiansdrosterone as well as C-17 side-chain containing compounds such as pregnenolone and 3beta-hydroxy-16alpha,17alpha-epoxypregn-5-en-20-one. 3beta-HSD/isomerase activity only occurs following lactonization of the steroidal ring-D. Presence of C-7 allylic hydroxylation, in either epimeric form, inhibits 3beta-HSD/isomerase activity. In Aspergillus tamarii, pregnenolone and 3beta-hydroxy-16alpha,17alpha-epoxypregn-5-en-20-one are metabolized solely through the putative 3beta-HSD/isomerase pathway	Aspergillus tamarii	?	-	?
