Fungal 17 beta-hydroxysteroid dehydrogenase.
Two representatives of each of different fungal taxonomic classes were tested for constitutive 17 beta-hydroxysteroid dehydrogenase (HSDH) activity and the results were positive in all cases. The enzyme was found to be regioselective for C17 of the steroid ring and 20 beta-HSDH activity was only detected in Trichoderma viride. In most cases the oxidative pathway is favoured over the reductive pathway. The possible role of this enzyme in fungi is discussed.
