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.
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 = 2 5'-
CC         deoxyadenosine + [[Fe-S] cluster scaffold protein] + 4 Fe(3+) + 2
CC         hydrogen sulfide + 2 L-methionine + N(6)-[(R)-dihydrolipoyl]-L-lysyl-
CC         [protein] + 2 reduced [2Fe-2S]-[ferredoxin]; Xref=Rhea:RHEA:16585,

CC   -!- COFACTOR:
CC       Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
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   -!- PATHWAY: Protein modification; protein lipoylation via endogenous
CC       pathway; protein N(6)-(lipoyl)lysine from octanoyl-[acyl-carrier-
CC       protein]: step 2/2.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
case not <AnyFeature:TransitC>
CC   -!- MISCELLANEOUS: This protein may be expected to contain an N-terminal
CC       transit peptide but none has been predicted.
end case
CC   -!- SIMILARITY: Belongs to the radical SAM superfamily. Lipoyl synthase
CC       family.
