KEGG   REACTION: R03176
Entry
R03176                      Reaction                               

Name
3beta-Hydroxy-delta5-steroid:NAD+ 3-oxidoreductase
Definition
3beta-Hydroxy-Delta5-steroid + NAD+ <=> 3-Oxo-Delta5-steroid + NADH + H+
Equation
Comment
many enzymes also have delta5-delat4-isomerase activity (see ec 5.3.3.1 or R02644) and convert 3beta-hydroxy-delta5-steroid into 3-oxo-delta4-steroid.
