Status
Reviewed-Annotation score: Annotation score: 3 out of 5-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

Catalytic activityi

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

Pathway:i(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.

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.
