dihydropteroate synthase; This model represents dihydropteroate synthase, the enzyme that catalyzes the second to last step in folic acid biosynthesis. The gene is usually designated folP (folic acid biosynthsis) or sul (sulfanilamide resistance). This model represents one branch of the family of pterin-binding enzymes (pfam00809) and of a cluster of dihydropteroate synthase and related enzymes (COG0294). Other members of pfam00809 and COG0294 are represented by model TIGR00284. [Biosynthesis of cofactors, prosthetic groups, and carriers, Folic acid]

DHPS subgroup of Pterin binding enzymes. DHPS (dihydropteroate synthase), a functional homodimer, catalyzes the condensation of p-aminobenzoic acid (pABA) in the de novo biosynthesis of folate, which is an essential cofactor in both nucleic acid and protein biosynthesis. Prokaryotes (and some lower eukaryotes) must synthesize folate de novo, while higher eukaryotes are able to utilize dietary folate and therefore lack DHPS. Sulfonamide drugs, which are substrate analogs of pABA, target DHPS.

Pterin binding enzyme; This family includes a variety of pterin binding enzymes that all adopt a TIM barrel fold. The family includes dihydropteroate synthase EC:2.5.1.15 as well as a group methyltransferase enzymes including methyltetrahydrofolate, corrinoid iron-sulfur protein methyltransferase (MeTr) that catalyzes a key step in the Wood-Ljungdahl pathway of carbon dioxide fixation. It transfers the N5-methyl group from methyltetrahydrofolate (CH3-H4folate) to a cob(I)amide centre in another protein, the corrinoid iron-sulfur protein. MeTr is a member of a family of proteins that includes methionine synthase and methanogenic enzymes that activate the methyl group of methyltetra-hydromethano(or -sarcino)pterin.

Pterin binding enzymes. This family includes dihydropteroate synthase (DHPS) and cobalamin-dependent methyltransferases such as methyltetrahydrofolate, corrinoid iron-sulfur protein methyltransferase (MeTr) and methionine synthase (MetH). DHPS, a functional homodimer, catalyzes the condensation of p-aminobenzoic acid (pABA) in the de novo biosynthesis of folate, which is an essential cofactor in both nucleic acid and protein biosynthesis. Prokaryotes (and some lower eukaryotes) must synthesize folate de novo, while higher eukaryotes are able to utilize dietary folate and therefore lack DHPS. Sulfonamide drugs, which are substrate analogs of pABA, target DHPS. Cobalamin-dependent methyltransferases catalyze the transfer of a methyl group via a methyl- cob(III)amide intermediate. These include MeTr, a functional heterodimer, and the folate binding domain of MetH.

of the residues that compose this conserved feature have been mapped to the query sequence.
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.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.
To view your query sequence embedded in that multiple sequence alignment, click on the colored bars in the Graphical Summary portion of the search results page,
or click on the triangles, if present, that represent functional sites (conserved features)
mapped to the query sequence.
Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.
(labeled illustration) Standard Display shows only the best scoring domain model from each source, in each hit category listed below for each region on the query sequence.
(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(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
(illustrated example)
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
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
the domain superfamily to which the specific and non-specific hits belong
