DE   2-hydroxyisoflavanone synthase.
AN   CYT93C.
AN   isoflavonoid synthase.
CA   (1) (2S)-liquiritigenin + reduced [NADPH--hemoprotein reductase] + O2 =
CA   (2R,3S)-2,4',7-trihydroxyisoflavanone + oxidized [NADPH--hemoprotein
CA   reductase] + H2O + H(+).
CA   (2) (2S)-naringenin + reduced [NADPH--hemoprotein reductase] + O2 =
CA   2-hydroxy-2,3-dihydrogenistein + oxidized [NADPH--hemoprotein reductase]
CA   + H2O + H(+).
CC   -!- A cytochrome P450 (heme thiolate) protein found in plants.
CC   -!- The reaction involves the migration of the 2-phenyl group of the
CC       flavanone to the 3-position of the isoflavanone.
CC   -!- The 2-hydroxyl group is derived from the oxygen molecule.
CC   -!- EC 4.2.1.105 acts on the products with loss of water and formation of
CC       genistein and daidzein, respectively.
CC   -!- Formerly EC 1.14.13.136.
