NCS1 family nucleobase:cation symporter-1 is an essential component in salvage pathways for nucleobases and related metabolites such as allantoin, uracil, thiamine, and nicotinamide riboside; similar to Escherichia coli putative allantoin permease
uncharacterized nucleobase-cation-symport-1 (NCS1) transporter subfamily, YbbW-like; solute-binding domain; NCS1s are essential components of salvage pathways for nucleobases and related metabolites; their known substrates include allantoin, uracil, thiamine, and nicotinamide riboside. This subfamily includes the putative allantoin transporter Escherichia coli YbbW (also known as GlxB2). NCS1s belong to a superfamily which also contains the solute carrier 5 family sodium/glucose transporters (SLC5s), and solute carrier 6 family neurotransmitter transporters (SLC6s).

NCS1 nucleoside transporter family; The Nucleobase:Cation Symporter-1 (NCS1) Family (TC 2.A.39) The NCS1 family consists of bacterial and yeast transporters for nucleobases including purines and pyrimidines. Members of this family possess twelve putative transmembrane a-helical spanners (TMSs). At least some of them have been shown to function in uptake by substrate:H+ symport mechanism.

nucleobase-cation-symport-1 (NCS1) transporters; solute-binding domain; NCS1s are essential components of salvage pathways for nucleobases and related metabolites; their known substrates include allantoin, uracil, thiamine, and nicotinamide riboside. This family includes Microbacterium liquefaciens Mhp1, a transporter that mediates the uptake of indolyl methyl- and benzyl-hydantoins as part of a metabolic salvage pathway for their conversion to amino acids. It also includes various Saccharomyces cerevisiae transporters: Fcy21p (Purine-cytosine permease), vitamin B6 transporter Tpn1, nicotinamide riboside transporter 1 (Nrt1p, also called Thi71p), Dal4p (allantoin permease), Fui1p (uridine permease), and Fur4p (uracil permease). Mhp1 has 12 transmembrane (TM) helices (an inverted topology repeat: TMs1-5 and TMs6-10, and TMs11-12; TMs numbered to conform to the solute carrier 6 family Aquifex aeolicus LeuT). NCS1s belong to a superfamily which also contains the solute carrier 5 family sodium/glucose transporters (SLC5s), and SLC6 neurotransmitter transporters.

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,

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
