high affinity sulphate transporter 1; The SulP family is a large and ubiquitous family with over 30 sequenced members derived from bacteria, fungi, plants and animals. Many organisms including Bacillus subtilis, Synechocystis sp, Saccharomyces cerevisiae, Arabidopsis thaliana and Caenorhabditis elegans possess multiple SulP family paralogues. Many of these proteins are functionally characterized, and all are sulfate uptake transporters. Some transport their substrate with high affinities, while others transport it with relatively low affinities. Most function by SO42- :H+symport, but SO42- :HCO3- antiport has been reported for the rat protein (spP45380). The bacterial proteins vary in size from 434 residues to 566 residues with one exception, a Mycobacterium tuberculosis protein with 784 residues. The eukaryotic proteins vary in size from 611 residues to 893 residues with one exception, a protein designated "early nodulin 70 protein" from Glycine max which is reported to be of 485 residues. Thus, the eukaryotic proteins are almost without exception larger than the prokaryotic proteins. These proteins exhibit 10-13 putative transmembrane a-helical spanners (TMSs) depending on the protein. The phylogenetic tree for the SulP family reveals five principal branches. Three of these are bacterial specific as follows: one bears a single protein from M. tuberculosis; a second bears two proteins, one from M. tuberculosis, the other from Synechocystis sp, and the third bears all remaining prokaryotic proteins. The remaining two clusters bear only eukaryotic proteins with the animal proteins all localized to one branch and the plant and fungal proteins localized to the other. The generalized transport reactions catalyzed by SulP family proteins are: (1) SO42- (out) + nH+ (out) --> SO42- (in) + nH+ (in). (2) SO42- (out) + nHCO3- (in) SO42- (in) + nHCO3- (out).

Sulfate permease family; This family of integral membrane proteins are known as the Sulfate Permease (SulP) family. SulP is a large family found in all domains of life. Although sulfate is a commonly transported ion there are many other activities in this family. See the TCDB description for a comprehensive summary.

Molybdate transporter of MFS superfamily; MFS_MOT1 is a family of molybdenate transporters. Molybdenum is an essential element that is taken up into the cell in the oxyanion molybdate. Molybdenum is used in the form of molybdopterin-cofactor, which participates in the active site of enzymes involved in key reactions of carbon, nitrogen, and sulfur metabolism.

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.

(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
