Entry
Name
7alpha-hydroxysteroid dehydrogenase;
7alpha-hydroxy steroid dehydrogenase;
7alpha-HSDH
Class
Oxidoreductases;
Acting on the CH-OH group of donors;
With NAD+ or NADP+ as acceptor
BRITE hierarchy
Sysname
7alpha-hydroxysteroid:NAD+ 7-oxidoreductase
Reaction(IUBMB)
cholate + NAD+ = 3alpha,12alpha-dihydroxy-7-oxo-5beta-cholan-24-oate + NADH + H+ [RN:
R02792 ]
Reaction(KEGG)
Substrate
Product
3alpha,12alpha-dihydroxy-7-oxo-5beta-cholan-24-oate [CPD:
C04643 ];
NADH [CPD:
C00004 ];
H+ [CPD:
C00080 ]
Comment
Catalyses the oxidation of the 7alpha-hydroxy group of bile acids and alcohols both in their free and conjugated forms. The Bacteroides fragilis and Clostridium enzymes can also utilize NADP+.
