Enzyme reactions

• Enzyme class: E.C.2.3.1.184 - acyl-homoserine-lactone synthase.
• Reaction: a fatty acyl-[ACP] + S-adenosyl-L-methionine = an N-acyl-L-homoserine lactone + S-methyl-5'-thioadenosine + holo-[ACP] + H⁺

fatty acyl-[ACP] + S-adenosyl-L-methionine = N-acyl-L-homoserine lactone (Bound ligand (Het Group name = NOO) matches with 42.11% similarity) + S-methyl-5'-thioadenosine + holo-[ACP] + H(+) (Bound ligand (Het Group name = MTA) corresponds exactly)
