NAME        8-Hydroxyfuranocoumarin 8-O-methyltransferase
CLASS       Transferases
            Transferring one-carbon groups
            Methyltransferases
SYSNAME     S-Adenosyl-L-methionine:8-hydroxyfuranocoumarin
            $ 8-O-methyltransferase
REACTION    S-Adenosyl-L-methionine + 8-Hydroxyfuranocoumarin =
            S-Adenosyl-L-homocysteine + 8-Methoxyfuranocoumarin
SUBSTRATE   S-Adenosyl-L-methionine
            8-Hydroxyfuranocoumarin
            Xanthotoxol
PRODUCT     S-Adenosyl-L-homocysteine
            8-Methoxyfuranocoumarin
            Xanthotoxin
COMMENT     Converts xanthotoxol into xanthotoxin.  Methylates the 8-hydroxyl
            of some hydroxy- and methylcoumarins, but has little activity on
            non-coumarin phenol.
