Protein CitXG

Gene

citXG

Organism
Leuconostoc mesenteroides subsp. cremoris
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Bifunctional enzyme that catalyzes formation of 2-(5''-triphosphoribosyl)-3'-dephosphocoenzyme-A, and then the transfer of this prosthetic group precursor to the apo-acyl carrier protein (gamma chain) of the citrate lyase to yield the holo-acyl carrier protein.By similarity

Catalytic activityi

2'-(5-triphosphoribosyl)-3'-dephospho-CoA + citrate lyase apo-[acyl-carrier protein] = citrate lyase holo-[acyl-carrier protein] + diphosphate.
ATP + 3'-dephospho-CoA = 2'-(5-triphospho-alpha-D-ribosyl)-3'-dephospho-CoA + adenine.

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.
