Entry
EC 1.14.21.8                Enzyme                                 

Name
pseudobaptigenin synthase
Class
Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With NADH or NADPH as one donor, and the other dehydrogenated
BRITE hierarchy
Sysname
calycosin,NADPH:oxygen oxidoreductase (methylenedioxy-bridge-forming)
Reaction(IUBMB)
(1) calycosin + NADPH + H+ + O2 = pseudobaptigenin + NADP+ + 2 H2O [RN:R07745];
(2) pratensein + NADPH + H+ + O2 = 5-hydroxypseudobaptigenin + NADP+ + 2 H2O [RN:R09602]
Reaction(KEGG)
Substrate
calycosin [CPD:C01562];
NADPH [CPD:C00005];
H+ [CPD:C00080];
O2 [CPD:C00007];
pratensein [CPD:C10520]
Product
pseudobaptigenin [CPD:C10522];
NADP+ [CPD:C00006];
H2O [CPD:C00001];
5-hydroxypseudobaptigenin [CPD:C19727]
Comment
A heme-thiolate enzyme (P-450) catalysing an oxidative reaction that does not incorporate oxygen into the product. Catalyses a step in the biosynthesis of (-)-maackiain, the main pterocarpan phytoalexin in chickpea (Cicer arietinum).
