Lipoate is an essential cofactor for key enzymes of oxidative metabolism. Mechanism of lipoate biosynthesis is similar to biotin biosynthesis. Octanoyltransferase facilitates the tranfer of octanoate moiety from octanoate-ACP to particular lysyl residues in lipoate-dependent enzymes. This process regenerates the acyl-carrier in the process, and create an octanylated domains in lipoate-dependent enzymes. Lipoyl synthase combines with S-adenosyl-L-methionine to generate an active lipoylated domain by converting the octanoyl side chain to an active lipoyl. Lipoyl synthase also split S-Adenosyl methionine (AdoMet) into 5'-deoxyadenosyl radical (later becomes 5'-deoxyadenosine by abstracting a hydrogen from a C-H bond) and L-methionine. L-methionine will undergo S-Adenosyl-L-Methionine Biosynthesis.
