Protein

Dephospho-CoA kinase

Gene

coaE

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the phosphorylation of the 3'-hydroxyl group of dephosphocoenzyme A to form coenzyme A.

Catalytic activityi

ATP + 3'-dephospho-CoA = ADP + CoA.

pH dependencei

Optimum pH is 8.5.

Pathwayi: coenzyme A biosynthesis

This protein is involved in step 5 of the subpathway that synthesizes CoA from (R)-pantothenate.
Proteins known to be involved in the 5 steps of the subpathway in this organism are:
  1. Pantothenate kinase (coaA)
  2. Coenzyme A biosynthesis bifunctional protein CoaBC (coaBC)
  3. Coenzyme A biosynthesis bifunctional protein CoaBC (coaBC)
  4. Phosphopantetheine adenylyltransferase (coaD)
  5. Dephospho-CoA kinase (coaE)
This subpathway is part of the pathway coenzyme A biosynthesis, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes CoA from (R)-pantothenate, the pathway coenzyme A biosynthesis and in Cofactor biosynthesis.

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 one 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.
