Costunolide synthase (EC 1.14.14.150) is an enzyme with systematic name germacra-1(10),4,11(13)-trien-12-oate,NADPH:oxygen oxidoreductase (6alpha-hydroxylating).[1] This enzyme catalyses the following chemical reaction
Costunolide synthase is a cytochrome P450 protein containing heme. It requires a partner cytochrome P450 reductase for functional expression. This uses nicotinamide adenine dinucleotide phosphate.[2] The starting material for this sesquiterpene lactone is produced from (+)-germacrene A by the enzyme germacrene A hydroxylase.[3]
