The mechanism of the isomerisation of delta 5-3,17-androstenedione by the isomerase (3-oxosteroid delta 4-delta 5-isomerase, EC 5.3.3.1) of Pseudomonas testosteroni has been reinvestigated with delta 5-[4-beta-2H]androstenedione as substrate in H2O and delta 5-androstenedione in 2H2O. A precise localisation of the label in delta 4-androstenendione has revealed that the previously reported 4 beta leads
