Protein

Lipoyl synthase, mitochondrial

Gene

Tb10.61.1530

Organism
Trypanosoma brucei brucei (strain 927/4 GUTat10.1)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-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

Miscellaneous

This protein may be expected to contain an N-terminal transit peptide but none has been predicted.UniRule annotation

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. no protein annotated in this organism
  2. Lipoyl synthase, mitochondrial (Tb10.61.1530)
This subpathway is part of the pathway protein lipoylation via endogenous pathway, which is itself part of Protein modification.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes protein N(6)-(lipoyl)lysine from octanoyl-[acyl-carrier-protein], the pathway protein lipoylation via endogenous pathway and in Protein modification.
