NAME        3,9-Dihydroxypterocarpan 6a-monooxygenase
            3,9-Dihydroxypterocarpan 6a-hydroxylase
CLASS       Oxidoreductases
            Acting on paired donors with incorporation of molecular oxygen
            With NADH or NADPH as one donor, and incorporation of one atom of
            oxygen
SYSNAME     (6aR,11aR)-3,9-Dihydroxypterocarpan,NADPH:oxygen oxidoreductase
            $ (6a-hydroxylating)
REACTION    (6aR,11aR)-3,9-Dihydroxypterocarpan + NADPH + O2 =
            (6aS,11aS)-3,6a,9-Trihydroxypterocarpan + NADP+ + H2O
SUBSTRATE   (6aR,11aR)-3,9-Dihydroxypterocarpan
            NADPH
            O2
PRODUCT     (6aS,11aS)-3,6a,9-Trihydroxypterocarpan
            NADP+
            H2O
COFACTOR    Heme
COMMENT     Possibly a heme-thiolate protein (P-450).  The product of the
            reaction is the biosynthetic precursor of the phytoalexin
