Comment typeDescription
Catalytic ActivityProtein 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. {ECO:0000255|HAMAP-Rule:MF_03129}.
CofactorName=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Evidence={ECO:0000255|HAMAP-Rule:MF_03129}; Note=Binds 2 [4Fe-4S] clusters per subunit. One cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L- methionine. {ECO:0000255|HAMAP-Rule:MF_03129};
FunctionCatalyzes 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. {ECO:0000255|HAMAP-Rule:MF_03129, ECO:0000269|PubMed:12062419}.
PathwayProtein modification; protein lipoylation via endogenous pathway; protein N(6)-(lipoyl)lysine from octanoyl-[acyl-carrier- protein]: step 2/2. {ECO:0000255|HAMAP-Rule:MF_03129}.
Sequence CautionSequence=AAM62684.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence={ECO:0000305}; Sequence=CAC08341.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
SimilarityBelongs to the radical SAM superfamily. Lipoyl synthase family. {ECO:0000255|HAMAP-Rule:MF_03129}.
Subcellular LocationPlastid, chloroplast {ECO:0000255|HAMAP- Rule:MF_03129, ECO:0000269|PubMed:12062419}.
Tissue SpecificityExpressed in roots, leaves and flowers. {ECO:0000269|PubMed:12062419}.
