uracil-xanthine permease; The Nucleobase:Cation Symporter-2 (NCS2) Family (TC 2.A.40) Most of the functionally characterized members of the NCS2 family are transporters specific for nucleobases including both purines and pyrimidines. However, two closely related rat members of the family, SVCT1 and SVCT2, localized to different tissues of the body, cotransport L-ascorbate and Na+ with a high degree of specificity and high affinity for the vitamin. The NCS2 family appears to be distantly related to the NCS1 family (TC #2.A.39). [Transport and binding proteins, Nucleosides, purines and pyrimidines]

pyrimidine utilization transport protein G; This protein is observed in operons extremely similar to that characterized in E. coli K-12 responsible for the import and catabolism of pyrimidines, primarily uracil. This protein is a member of the uracil-xanthine permease family defined by TIGR00801. As well as the The Nucleobase:Cation Symporter-2 (NCS2) Family (TC 2.A.40).

xanthine permease; All the seed members of this model are observed adjacent to genes for either xanthine phosphoribosyltransferase (for the conversion of xanthine to guanine, GenProp0696) or genes for the conversion of xanthine to urate and its concomitant catabolism (GenProp0640, GenProp0688, GenProp0686 and GenProp0687). A number of sequences scoring higher than trusted to this model are found in different genomic contexts, and the possibility exist that these transport related compounds in addition to or instead of xanthine itself. The outgroup to this family are sequences which are characterized as uracil permeases or are adjacent to established uracil phosphoribosyltransferases.

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
multi-domain models that were computationally detected and are likely to contain multiple single domains
