Probable phosphopantothenoylcysteine decarboxylase

Gene

coaC

Organism
Streptococcus mutans serotype c (strain ATCC 700610 / UA159)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the decarboxylation of 4'-phosphopantothenoylcysteine to 4'-phosphopantetheine.

Catalytic activityi

N-((R)-4'-phosphopantothenoyl)-L-cysteine = pantotheine 4'-phosphate + CO2.

Pathwayi: coenzyme A biosynthesis

This protein is involved in step 3 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. no protein annotated in this organism
  3. Probable phosphopantothenoylcysteine decarboxylase (coaC)
  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.
