Tpt phosphate/phosphoenolpyruvate translocator; The 6-8 TMS Triose-phosphate Transporter (TPT) Family (TC 2.A.7.9)Functionally characterized members of the TPT family are derived from the inner envelope membranes of chloroplasts and nongreen plastids of plants. However,homologues are also present in yeast. Saccharomyces cerevisiae has three functionally uncharacterized TPT paralogues encoded within its genome. Under normal physiologicalconditions, chloroplast TPTs mediate a strict antiport of substrates, frequently exchanging an organic three carbon compound phosphate ester for inorganic phosphate (Pi).Normally, a triose-phosphate, 3-phosphoglycerate, or another phosphorylated C3 compound made in the chloroplast during photosynthesis, exits the organelle into thecytoplasm of the plant cell in exchange for Pi. However, experiments with reconstituted translocator in artificial membranes indicate that transport can also occur by achannel-like uniport mechanism with up to 10-fold higher transport rates. Channel opening may be induced by a membrane potential of large magnitude and/or by high substrateconcentrations. Nongreen plastid and chloroplast carriers, such as those from maize endosperm and root membranes, mediate transport of C3 compounds phosphorylated atcarbon atom 2, particularly phosphenolpyruvate, in exchange for Pi. These are the phosphoenolpyruvate:Pi antiporters (PPT). Glucose-6-P has also been shown to be asubstrate of some plastid translocators (GPT). The three types of proteins (TPT, PPT and GPT) are divergent in sequence as well as substrate specificity, but their substratespecificities overlap. [Hypothetical proteins, Conserved]

solute carrier family 35 member C2, member of the triose-phosphate transporter family; Solute carrier family 35 member C2 (S35C2 or Slc35c2), also called ovarian cancer-overexpressed gene 1 protein (OVCOV1), is a member of the triose-phosphate transporter (TPT) family, which is part of the drug/metabolite transporter (DMT) superfamily. It may function either as a GDP-fucose transporter that competes with Slc35c1 (S35C1) for GDP-fucose, or a factor that otherwise enhances the fucosylation of Notch and is required for optimal Notch signaling in mammalian cells.

EamA-like transporter family; This family includes many hypothetical membrane proteins of unknown function. Many of the proteins contain two copies of the aligned region. The family used to be known as DUF6. Members of this family usually carry 5+5 transmembrane domains, and this domain attempts to model five of these.

(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.
