2-hydroxyisoflavanone synthase activity
Catalysis of the reactions: liquiritigenin + O2 + [reduced NADPH--hemoprotein reductase] = 2,4',7-trihydroxyisoflavanone + H2O + [oxidized NADPH--hemoprotein reductase] and (2S)-naringenin + O2 + [reduced NADPH--hemoprotein reductase] = 2,4',5,7-tetrahydroxyisoflavanone + H2O + [oxidized NADPH--hemoprotein reductase].
