General annotation (Comments)

Function

Catalyzes the radical-mediated insertion of two sulfur atoms into the C-6 and C-8 positions of the octanoyl moiety bound to the lipoyl domains of lipoate-dependent enzymes, thereby converting the octanoylated domains into lipoylated derivatives By similarity. HAMAP-Rule MF_03123

Catalytic activity

Protein N(6)-(octanoyl)lysine + 2 sulfur-(sulfur carrier) + 2 S-adenosyl-L-methionine = protein N(6)-(lipoyl)lysine + 2 (sulfur carrier) + 2 L-methionine + 2 5'-deoxyadenosine. HAMAP-Rule MF_03123

Cofactor

Binds 2 4Fe-4S clusters per subunit. One cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine By similarity.

Pathway

Protein modification; protein lipoylation via endogenous pathway; protein N(6)-(lipoyl)lysine from octanoyl-[acyl-carrier-protein]: step 2/2. HAMAP-Rule MF_03123

Subcellular location

Plastidapicoplast By similarity HAMAP-Rule MF_03123.

Sequence similarities

Belongs to the radical SAM superfamily. Lipoyl synthase family.
