Protein

2-dehydropantoate 2-reductase

Gene

panE

Organism
Escherichia coli O157:H7
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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

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.
