8-hydroxyfuranocoumarin 8-O-methyltransferase (EC 2.1.1.70, furanocoumarin 8-methyltransferase, furanocoumarin 8-O-methyl-transferase, xanthotoxol 8-O-methyltransferase, XMT, SAM:xanthotoxol O-methyltransferase, S-adenosyl-L-methionine:8-hydroxyfuranocoumarin 8-O-methyltransferase, xanthotoxol methyltransferase, xanthotoxol O-methyltransferase, S-adenosyl-L-methionine:xanthotoxol O-methyltransferase, S-adenosyl-L-methionine-xanthotoxol O-methyltransferase) is an enzyme with systematic name S-adenosyl-L-methionine:8-hydroxyfurocoumarin 8-O-methyltransferase.[1][2][3][4] This enzyme catalyses the following chemical reaction
- (1) S-adenosyl-L-methionine + an 8-hydroxyfurocoumarin S-adenosyl-L-homocysteine + an 8-methoxyfurocoumarin (general reaction)
- (2) S-adenosyl-L-methionine + xanthotoxol S-adenosyl-L-homocysteine + xanthotoxin
8-hydroxyfuranocoumarin 8-O-methyltransferase converts xanthotoxol into xanthotoxin.
