Isoflavonoid synthase

2-hydroxyisoflavanone synthase (, CYT93C, IFS, isoflavonoid synthase) is an enzyme with systematic name liquiritigenin,NADPH:oxygen oxidoreductase (hydroxylating, aryl migration). This enzyme catalyses the following chemical reactions:


 * liquiritigenin + O2 + NADPH + H+ $$\rightleftharpoons$$ 2,4',7-trihydroxyisoflavanone + H2O + NADP+

and
 * (2S)-naringenin + O2 + NADPH + H+ $$\rightleftharpoons$$ 2,4',5,7-tetrahydroxyisoflavanone + H2O + NADP+

Isoflavonoid synthase requires cytochrome P450.
