2-dehydropantoate 2-reductase; This model describes enzymes that perform as 2-dehydropantoate 2-reductase, one of four enzymes required for the de novo biosynthesis of pantothenate (vitamin B5) from Asp and 2-oxoisovalerate. Although few members of the seed alignment are characterized experimentally, nearly all from complete genomes are found in a genome-wide (but not local) context of all three other pantothenate-biosynthetic enzymes (TIGR00222, TIGR00018, TIGR00223). The gene encoding this enzyme is designated apbA in Salmonella typhimurium and panE in Escherichia coli; this protein functions as a monomer and functions in the alternative pyrimidine biosynthetic, or APB, pathway, used to synthesize the pyrimidine moiety of thiamine. Note, synthesis of the pyrimidine moiety of thiamine occurs either via the first five steps in de novo purine biosynthesis, which uses the pur gene products, or through the APB pathway. Note that this family includes both NADH and NADPH-dependent enzymes, and enzymes with broad specificity, such as a D-mandelate dehydrogease that is also a 2-dehydropantoate 2-reductase.

Ketopantoate reductase PanE/ApbA C terminal; This is a family of 2-dehydropantoate 2-reductases also known as ketopantoate reductases, EC:1.1.1.169. The reaction catalyzed by this enzyme is: (R)-pantoate + NADP(+) <=> 2-dehydropantoate + NADPH. AbpA catalyzes the NADPH reduction of ketopantoic acid to pantoic acid in the alternative pyrimidine biosynthetic (APB) pathway. ApbA and PanE are allelic. ApbA, the ketopantoate reductase enzyme is required for the synthesis of thiamine via the APB biosynthetic pathway.

Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.
The thumbnail image, if present, provides an approximate view of the feature's location in 3 dimensions.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.

(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold

and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
