EC 2.3.2.35     
Accepted name: capsaicin synthase
Reaction: (6E)-8-methylnon-6-enoyl-CoA + vanillylamine = CoA + capsaicin
Other name(s): CS (gene name) (ambiguous); Pun1 (locus name)
Systematic name: (6E)-8-methylnon-6-enoyl-CoA:vanillylamine 8-methylnon-6-enoyltransferase
Comments: The enzyme, found only in plants that belong to the Capsicum genus, catalyses the last step in the biosynthesis of capsaicinoids. The enzyme catalyses the acylation of vanillylamine by a branched-chain fatty acid. The exact structure of the fatty acid determines the type of capsaicinoid formed.
