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 | Reaction=[[Fe-S] cluster scaffold protein carrying a second [4Fe- 4S](2+) cluster] + 4 H(+) + N(6)-octanoyl-L-lysyl-[protein] + 2 oxidized [2Fe-2S]-[ferredoxin] + 2 S-adenosyl-L-methionine = 2 5'- deoxyadenosine + [[Fe-S] cluster scaffold protein] + 4 Fe(3+) + 2 hydrogen sulfide + 2 L-methionine + N(6)-[(R)-dihydrolipoyl]-L-lysyl- [protein] + 2 reduced [2Fe-2S]-[ferredoxin]; Xref=Rhea:RHEA:16585, Rhea:RHEA-COMP:9928, Rhea:RHEA-COMP:10000, Rhea:RHEA-COMP:10001, Rhea:RHEA-COMP:10475, Rhea:RHEA-COMP:14568, Rhea:RHEA-COMP:14569, ChEBI:CHEBI:15378, ChEBI:CHEBI:17319, ChEBI:CHEBI:29034, ChEBI:CHEBI:29919, ChEBI:CHEBI:33722, ChEBI:CHEBI:33737, ChEBI:CHEBI:33738, ChEBI:CHEBI:57844, ChEBI:CHEBI:59789, ChEBI:CHEBI:78809, ChEBI:CHEBI:83100; EC=2.8.1.8; |
COFACTOR | Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; 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 N(6)-(lipoyl)lysine from octanoyl-[acyl-carrier- protein]: step 2/2. |

SUBCELLULAR LOCATION | Plastid, organellar chromatophore. |
else case <OC:Apicomplexa> | |
SUBCELLULAR LOCATION | Plastid, apicoplast. |

SUBCELLULAR LOCATION | Mitochondrion. |
end case | |
case not <OC:Apicomplexa> and not <OG:Organellar chromatophore> and not <AnyFeature:TransitM> | |
MISCELLANEOUS | This protein may be expected to contain an N-terminal transit peptide but none has been predicted. |
end case | |
SIMILARITY | Belongs to the radical SAM superfamily. Lipoyl synthase family. |
