Pantothenate synthetase

Gene

panC

Organism
Roseobacter denitrificans (strain ATCC 33942 / OCh 114) (Erythrobacter sp. (strain OCh 114)) (Roseobacter denitrificans)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the condensation of pantoate with beta-alanine in an ATP-dependent reaction via a pantoyl-adenylate intermediate.UniRule annotation

Miscellaneous

The reaction proceeds by a bi uni uni bi ping pong mechanism.UniRule annotation

Catalytic activityi

ATP + (R)-pantoate + beta-alanine = AMP + diphosphate + (R)-pantothenate.UniRule annotation

Pathwayi: (R)-pantothenate biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes (R)-pantothenate from (R)-pantoate and beta-alanine.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Pantothenate synthetase (panC)
This subpathway is part of the pathway (R)-pantothenate 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 (R)-pantothenate from (R)-pantoate and beta-alanine, the pathway (R)-pantothenate biosynthesis and in Cofactor biosynthesis.
