Organism
Shigella flexneri
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the NADPH-dependent reduction of ketopantoate into pantoic acid.By similarity

Catalytic activityi

(R)-pantoate + NADP+ = 2-dehydropantoate + NADPH.

Pathwayi: (R)-pantothenate biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes (R)-pantoate from 3-methyl-2-oxobutanoate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. 3-methyl-2-oxobutanoate hydroxymethyltransferase (panB)
  2. 2-dehydropantoate 2-reductase (panE)
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)-pantoate from 3-methyl-2-oxobutanoate, the pathway (R)-pantothenate 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.
