Entry
EC 1.17.99.11               Enzyme                                 
Name
3-oxo-Delta1-steroid hydratase/dehydrogenase;
atcABC (gene names)
Class
Oxidoreductases;
Acting on CH or CH2 groups;
With unknown physiological acceptors
Sysname
3-oxo-Delta1-steroid:acceptor 1-oxidoreductase
Reaction(IUBMB)
a 3-oxo-Delta1-steroid + H2O + acceptor = a steroid 1,3-dione + reduced acceptor (overall reaction) [RN:R12678];
(1a) a 3-oxo-Delta1-steroid + H2O = a 1-hydroxy-3-oxo-steroid [RN:R12679];
(1b) a 1-hydroxy-3-oxo-steroid + acceptor = a steroid 1,3-dione + reduced acceptor [RN:R12680]
Reaction(KEGG)
R12678 R12679 R12680
Substrate
3-oxo-Delta1-steroid [CPD:C02941];
H2O [CPD:C00001];
acceptor [CPD:C00028];
1-hydroxy-3-oxo-steroid [CPD:C22327]
Product
steroid 1,3-dione [CPD:C22326];
reduced acceptor [CPD:C00030];
1-hydroxy-3-oxo-steroid [CPD:C22327]
Comment
A molybdenum enzyme. The enzyme, characterized from the bacterium Steroidobacter denitrificans, is involved in the anaetrobic degradation of steroids. It is specific to 3-oxo-Delta1-steroids such as androsta-1-ene-3,17-dione and Delta1-dihydrotestosterone and does not act on 3-oxo-Delta4-steroids.
