Protein

Lipoyl synthase, mitochondrial

Gene

LIP1

Organism
Ricinus communis (Castor bean)
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.By similarity

Catalytic activityi

Protein 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.

Cofactori

[4Fe-4S] clusterBy similarityNote: Binds 2 [4Fe-4S] clusters per subunit. One cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine.By similarity

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.
