Functioni

Catalytic activityi

ATP + (R)-pantoate + beta-alanine = AMP + diphosphate + (R)-pantothenate.
ATP + (d)CMP = ADP + (d)CDP.

Pathwayi: (R)-pantothenate biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes (R)-pantothenate from (R)-pantoate and beta-alanine.
Proteins known to be involved in this subpathway in this organism are:
  1. Bifunctional pantoate ligase/cytidylate kinase (panC/cmk)
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 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.
