Protein

Lipoyl synthase

Gene

lipA

Organism
Burkholderia thailandensis
Status
Unreviewed-Annotation score: -Protein inferred from homologyi

Functioni

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.UniRule annotation

Caution

The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.Imported

Catalytic activityi

Protein N6-(octanoyl)lysine + 2 sulfur-(sulfur carrier) + 2 S-adenosyl-L-methionine + 2 reduced [2Fe-2S] ferredoxin = protein N6-(lipoyl)lysine + 2 (sulfur carrier) + 2 L-methionine + 2 5'-deoxyadenosine + 2 oxidized [2Fe-2S] ferredoxin.UniRule annotation

Cofactori

[4Fe-4S] clusterUniRule annotationNote: Binds 2 [4Fe-4S] clusters per subunit. One cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine.UniRule annotation

Pathwayi: protein lipoylation via endogenous pathway

This protein is involved in step 2 of the subpathway that synthesizes protein N(6)-(lipoyl)lysine from octanoyl-[acyl-carrier-protein].UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Octanoyltransferase (lipB)
  2. Lipoyl synthase (lipA), Lipoyl synthase (lipA)
This subpathway is part of the pathway protein lipoylation via endogenous pathway, which is itself part of Protein modification.
