EC 1.14.19.63 Details
EC number
1.14.19.63
Accepted name
pseudobaptigenin synthase
Reaction
(1) calycosin + [reduced NADPH—hemoprotein reductase] + O2 = pseudobaptigenin + [oxidized NADPH—hemoprotein reductase] + 2 H2O;;(2) pratensein + [reduced NADPH-hemoprotein reductase] + O2 = 5-hydroxypseudobaptigenin + [oxidized NADPH—hemoprotein reductase] + 2 H2O
Systematic name
calycosin,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (methylenedioxy-bridge-forming)
Comment
A cytochrome P-450 (heme-thiolate) enzyme 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).
History
created 2011 as EC 1.14.21.8, transferred 2018 to EC 1.14.19.63
