Function
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.
Catalytic activity
- [[Fe-S] cluster scaffold protein carrying a second [4Fe-4S]2+ cluster] + 4 H+ + N6-octanoyl-L-lysyl-[protein] + 2 oxidized [2Fe-2S]-[ferredoxin] + 2 S-adenosyl-L-methionine = 2 5'-deoxyadenosine + [[Fe-S] cluster scaffold protein] + 4 Fe3+ + 2 hydrogen sulfide + 2 L-methionine + N6-[(R)-dihydrolipoyl]-L-lysyl-[protein] + 2 reduced [2Fe-2S]-[ferredoxin]

Cofactor
Note: Binds 2 [4Fe-4S] clusters per subunit. One cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine.
Pathway
Protein modification; protein lipoylation via endogenous pathway; protein N6-(lipoyl)lysine from octanoyl-[acyl-carrier-protein]: step 2/2.
