Gene

lipA

Organism
Laribacter hongkongensis (strain HLHK9)
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

Catalytic activityi

Protein N(6)-(octanoyl)lysine + 2 sulfur-(sulfur carrier) + 2 S-adenosyl-L-methionine + 2 reduced [2Fe-2S] ferredoxin = protein N(6)-(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

Pathway:iprotein 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)
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.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
