CC -!- FUNCTION: Catalyzes the radical-mediated insertion of two sulfur atoms
CC into the C-6 and C-8 positions of the octanoyl moiety bound to the
CC lipoyl domains of lipoate-dependent enzymes, thereby converting the
CC octanoylated domains into lipoylated derivatives. {ECO:0000255|HAMAP-
CC Rule:MF_00206}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[[Fe-S] cluster scaffold protein carrying a second [4Fe-
CC 4S](2+) cluster] + 4 H(+) + N(6)-octanoyl-L-lysyl-[protein] + 2
CC oxidized [2Fe-2S]-[ferredoxin] + 2 S-adenosyl-L-methionine = (R)-
CC N(6)-dihydrolipoyl-L-lysyl-[protein] + 2 5'-deoxyadenosine + [[Fe-S]
CC cluster scaffold protein] + 4 Fe(3+) + 2 hydrogen sulfide + 2 L-
CC methionine + 2 reduced [2Fe-2S]-[ferredoxin]; Xref=Rhea:RHEA:16585,

CC Evidence={ECO:0000255|HAMAP-Rule:MF_00206};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00206};
CC Note=Binds 2 [4Fe-4S] clusters per subunit. One cluster is coordinated
CC with 3 cysteines and an exchangeable S-adenosyl-L-methionine.
CC {ECO:0000255|HAMAP-Rule:MF_00206};
CC -!- PATHWAY: Protein modification; protein lipoylation via endogenous
CC pathway; protein N(6)-(lipoyl)lysine from octanoyl-[acyl-carrier-
CC protein]: step 2/2. {ECO:0000255|HAMAP-Rule:MF_00206}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00206}.
CC -!- SIMILARITY: Belongs to the radical SAM superfamily. Lipoyl synthase
CC family. {ECO:0000255|HAMAP-Rule:MF_00206}.
