ID 1.14.19.63 DE pseudobaptigenin synthase. CA (1) calycosin + reduced [NADPH--hemoprotein reductase] + O2 = CA pseudobaptigenin + oxidized [NADPH--hemoprotein reductase] + 2 H2O + CA H(+). CA (2) pratensein + reduced [NADPH--hemoprotein reductase] + O2 = CA 5-hydroxypseudobaptigenin + oxidized [NADPH--hemoprotein reductase] + CA 2 H2O + H(+). CC -!- A cytochrome P450 (heme-thiolate) enzyme catalyzing an oxidative CC reaction that does not incorporate oxygen into the product. CC -!- Catalyzes a step in the biosynthesis of (-)-maackiain, the main CC pterocarpan phytoalexin in chickpea (Cicer arietinum). CC -!- Formerly EC 1.14.21.8. //
