With NAD+ or NADP+ as acceptor
BRITE hierarchy
Sysname
(1'S,5'S)-hydroxyaverantin:NAD+ oxidoreductase
Reaction(IUBMB)
(1) (1'S,5'S)-hydroxyaverantin + NAD+ = 5'-oxoaverantin + NADH + H+ [RN:R10310];
(2) (1'S,5'R)-hydroxyaverantin + NAD+ = 5'-oxoaverantin + NADH + H+ [RN:R10311]
Reaction(KEGG)
Substrate
(1'S,5'S)-hydroxyaverantin [CPD:C20500];
NAD+ [CPD:C00003];
(1'S,5'R)-hydroxyaverantin [CPD:C20501]
Product
5'-oxoaverantin [CPD:C20502];
NADH [CPD:C00004];
H+ [CPD:C00080]
Comment
Isolated from the aflatoxin-producing mold Aspergillus parasiticus [2]. Involved in aflatoxin biosynthesis. 5'-Oxoaverantin will spontaneously form averufin by intramolecular ketalisation. cf. EC 4.2.1.142, 5'-oxoaverantin cyclase.
