ID   1.17.99.11
DE   3-oxo-Delta(1)-steroid hydratase/dehydrogenase.
CA   A + a 3-oxo-Delta(1)-steroid + H2O = a steroid 1,3-dione + AH2.
CC   -!- A molybdenum enzyme.
CC   -!- The enzyme, characterized from the bacterium Steroidobacter
CC       denitrificans, is involved in the anaetrobic degradation of steroids.
CC   -!- It is specific to 3-oxo-Delta(1)-steroids such as androsta-1-ene-
CC       3,17-dione and Delta(1)-dihydrotestosterone and does not act on
CC       3-oxo-Delta(4)-steroids.
