P-type heavy metal-transporting ATPase, similar to human copper-transporting ATPases, ATP7A and ATP7B; The mammalian copper-transporting P-type ATPases, ATP7A and ATP7B are key molecules required for the regulation and maintenance of copper homeostasis. Menkes and Wilson diseases are caused by mutation in ATP7A and ATP7B respectively. This subfamily includes other copper-transporting ATPases such as: Bacillus subtilis CopA , Archeaoglobus fulgidus CopA, and Saccharomyces cerevisiae Ccc2p. This subclass of P-type ATPase is also referred to as CPx-type ATPases because their amino acid sequences contain a characteristic CPC or CPH motif associated with a stretch of hydrophobic amino acids and N-terminal ion-binding sequences. This subfamily belongs to the P-type ATPases, a large family of integral membrane transporters that are of critical importance in all kingdoms of life. They generate and maintain (electro-) chemical gradients across cellular membranes, by translocating cations, heavy metals and lipids, and are distinguished from other main classes of transport ATPases (F- , V- , and ABC- type) by the formation of a phosphorylated (P-) intermediate state in the catalytic cycle.

copper-(or silver)-translocating P-type ATPase; This model describes the P-type ATPase primarily responsible for translocating copper ions accross biological membranes. These transporters are found in prokaryotes and eukaryotes. This model encompasses those species which pump copper ions out of cells or organelles (efflux pumps such as CopA of Escherichia coli) as well as those which pump the ion into cells or organelles either for the purpose of supporting life in extremely low-copper environments (for example CopA of Enterococcus hirae) or for the specific delivery of copper to a biological complex for which it is a necessary component (for example FixI of Bradyrhizobium japonicum, or CtaA and PacS of Synechocystis). The substrate specificity of these transporters may, to a varying degree, include silver ions (for example, CopA from Archaeoglobus fulgidus). Copper transporters from this family are well known as the genes which are mutated in two human disorders of copper metabolism, Wilson's and Menkes' diseases. The sequences contributing to the seed of this model are all experimentally characterized. The copper P-type ATPases have been characterized as Type IB based on a phylogenetic analysis which combines the copper-translocating ATPases with the cadmium-translocating species. This model and that describing the cadmium-ATPases (TIGR01512) are well separated, and thus we further type the copper-ATPases as IB1 (and the cadmium-ATPases as IB2). Several sequences which have not been characterized experimentally fall just below the cutoffs for both of these models (SP|Q9CCL1 from Mycobacterium leprae, GP|13816263 from Sulfolobus solfataricus, OMNI|NTL01CJ01098 from Campylobacter jejuni, OMNI|NTL01HS01687 from Halobacterium sp., GP|6899169 from Ureaplasma urealyticum and OMNI|HP1503 from Helicobacter pylori). Accession PIR|A29576 from Enterococcus faecalis scores very high against this model, but yet is annotated as an "H+/K+ exchanging ATPase". BLAST of this sequence does not hit anything else annotated in this way. This error may come from the characterization paper published in 1987. Accession GP|7415611 from Saccharomyces cerevisiae appears to be mis-annotated as a cadmium resistance protein. Accession OMNI|NTL01HS00542 from Halobacterium which scores above trusted for this model is annotated as "molybdenum-binding protein" although no evidence can be found for this classification.

Heavy-metal-associated domain (HMA) is a conserved domain of approximately 30 amino acid residues found in a number of proteins that transport or detoxify heavy metals, for example, the CPx-type heavy metal ATPases and copper chaperones. HMA domain contains two cysteine residues that are important in binding and transfer of metal ions, such as copper, cadmium, cobalt and zinc. In the case of copper, stoichiometry of binding is one Cu+ ion per binding domain. Repeats of the HMA domain in copper chaperone has been associated with Menkes/Wilson disease due to binding of multiple copper ions.

ATPase, P-type (transporting), HAD superfamily, subfamily IC; The P-type ATPases are a large family of trans-membrane transporters acting on charged substances. The distinguishing feature of the family is the formation of a phosphorylated intermediate (aspartyl-phosphate) during the course of the reaction. Another common name for these enzymes is the E1-E2 ATPases based on the two isolable conformations: E1 (unphosphorylated) and E2 (phosphorylated). Generally, P-type ATPases consist of only a single subunit encompassing the ATPase and ion translocation pathway, however, in the case of the potassium (TIGR01497) and sodium/potassium (TIGR01106) varieties, these functions are split between two subunits. Additional small regulatory or stabilizing subunits may also exist in some forms. P-type ATPases are nearly ubiquitous in life and are found in numerous copies in higher organisms (at least 45 in Arabidopsis thaliana, for instance). Phylogenetic analyses have revealed that the P-type ATPase subfamily is divided up into groups based on substrate specificities and this is represented in the various subfamily and equivalog models that have been made: IA (K+) TIGR01497, IB (heavy metals) TIGR01525, IIA1 (SERCA-type Ca++) TIGR01116, IIA2 (PMR1-type Ca++) TIGR01522, IIB (PMCA-type Ca++) TIGR01517, IIC (Na+/K+, H+/K+ antiporters) TIGR01106, IID (fungal-type Na+ and K+) TIGR01523, IIIA (H+) TIGR01647, IIIB (Mg++) TIGR01524, IV (phospholipid, flippase) TIGR01652 and V (unknown specificity) TIGR01657. The crystal structure of one calcium-pumping ATPase and an analysis of the fold of the catalytic domain of the P-type ATPases have been published. These reveal that the catalytic core of these enzymes is a haloacid dehalogenase(HAD)-type aspartate-nucleophile hydrolase. The location of the ATP-binding loop in between the first and second HAD conserved catalytic motifs defines these enzymes as members of subfamily I of the HAD superfamily (see also TIGR01493, TIGR01509, TIGR01549, TIGR01544 and TIGR01545). Based on these classifications, the P-type ATPase _superfamily_ corresponds to the IC subfamily of the HAD superfamily.

In E. coli and other species, this complex consists of the proteins KdpA, KdpB, KdpC and KdpF. KdpB is the ATPase subunit, while KdpA is the potassium-ion translocating subunit. The function of KdpC is unclear, although cit has been suggested to couple the ATPase subunit to the ion-translocating subunit, while KdpF serves to stabilize the complex. The potassium P-type ATPases have been characterized as Type IA based on a phylogenetic analysis which places this clade closest to the heavy-metal translocating ATPases (Type IB). Others place this clade closer to the Na+/K+ antiporter type (Type IIC) based on physical characteristics. This model is very clear-cut, with a strong break between trusted hits and noise. All members of the seed alignment, from Clostridium, Anabaena and E. coli are in the characterized table. One sequence above trusted, OMNI|NTL01TA01282, is apparently mis-annotated in the primary literature, but properly annotated by TIGR.

magnesium transporting ATPase (MgtA), similar to Escherichia coli MgtA and Salmonella typhimurium MgtA; MgtA is a membrane protein which actively transports Mg(2+) into the cytosol with its electro-chemical gradient rather than against the gradient as other cation transporters do. It may act both as a transporter and as a sensor for Mg(2+). In Salmonella typhimurium and Escherichia coli, the two-component system PhoQ/PhoP regulates the transcription of the mgtA gene by sensing Mg(2+) concentrations in the periplasm. MgtA is activated by cardiolipin and it highly sensitive to free magnesium in vitro.

animal plasma membrane Ca2(+)-ATPases (PMCA), similar to human ATP2B1-4/PMCA1-4, and related Ca2(+)-ATPases including Saccharomyces cerevisiae vacuolar PMC1; Animal PMCAs function to export Ca(2+) from cells and play a role in regulating Ca(2+) signals following stimulus induction and in preventing calcium toxicity. Many PMCA pump variants exist due to alternative splicing of transcripts. PMCAs are regulated by the binding of calmodulin or by kinase-mediated phosphorylation. Saccharomyces cerevisiae vacuolar transporter Pmc1p facilitates the accumulation of Ca2+ into vacuoles. Pmc1p is not regulated by direct calmodulin binding but responds to the calmodulin/calcineurin-signaling pathway and is controlled by the transcription factor complex Tcn1p/Crz1p. Similarly, the expression of the gene for Dictyostelium discoideum Ca(2+)-ATPase PAT1, patA, is under the control of a calcineurin-dependent transcription factor. Plant vacuolar Ca(2+)-ATPases, are regulated by direct-calmodulin binding. Plant Ca(2+)-ATPases are present at various cellular locations including the plasma membrane, endoplasmic reticulum, chloroplast and vacuole.

sarco/endoplasmic reticulum Ca(2+)-ATPase (SERCA), similar to mammalian ATP2A1-3/SERCA1-3; SERCA is a transmembrane (Ca2+)-ATPase and a major regulator of Ca(2+) homeostasis and contractility in cardiac and skeletal muscle. It re-sequesters cytoplasmic Ca(2+) to the sarco/endoplasmic reticulum store, thereby also terminating Ca(2+)-induced signaling such as in muscle contraction. Three genes (ATP2A1-3/SERCA1-3) encode SERCA pumps in mammals, further isoforms exist due to alternative splicing of transcripts.

This subfamily includes all four isotopes of the human alpha subunit: (alpha1-alpha4, encoded by the ATP1A1- ATP1A4 genes). Na(+)/K(+)-ATPase functions chiefly as an ion pump, hydrolyzing one molecule of ATP to pump three Na(+) out of the cell in exchange for two K(+)entering the cell per pump cycle. In addition Na(+)/K(+)-ATPase acts as a signal transducer.

sodium or proton efflux -- potassium uptake antiporter, P-type ATPase, alpha subunit; This model describes the P-type ATPases responsible for the exchange of either protons or sodium ions for potassium ions across the plasma membranes of eukaryotes. Unlike most other P-type ATPases, members of this subfamily require a beta subunit for activity. This model encompasses eukaryotes and consists of two functional types, a Na/K antiporter found widely distributed in eukaryotes and a H/K antiporter found only in vertebrates. The Na+ or H+/K+ antiporter P-type ATPases have been characterized as Type IIC based on a published phylogenetic analysis. Sequences from Blastocladiella emersonii (GP|6636502, GP|6636502 and PIR|T43025), C. elegans (GP|2315419, GP|6671808 and PIR|T31763) and Drosophila melanogaster (GP|7291424) score below trusted cutoff, apparently due to long branch length (excessive divergence from the last common ancestor) as evidenced by a phylogenetic tree. Experimental evidence is needed to determine whether these sequences represent ATPases with conserved function. Aside from fragments, other sequences between trusted and noise appear to be bacterial ATPases of unclear lineage, but most likely calcium pumps.

Heavy-metal-associated domain (HMA) is a conserved domain of approximately 30 amino acid residues found in a number of proteins that transport or detoxify heavy metals, for example, the CPx-type heavy metal ATPases and copper chaperones. HMA domain contains two cysteine residues that are important in binding and transfer of metal ions, such as copper, cadmium, cobalt and zinc. In the case of copper, stoichiometry of binding is one Cu+ ion per binding domain. Repeats of the HMA domain in copper chaperone has been associated with Menkes/Wilson disease due to binding of multiple copper ions.

Haloacid Dehalogenase superfamily, subfamily IB, phosphoserine phosphatase-like; This model represents a subfamily of the Haloacid Dehalogenase superfamily of aspartate-nucleophile hydrolases. Subfamily IA, B, C and D are distinguished from the rest of the superfamily by the presence of a variable domain between the first and second conserved catalytic motifs. In subfamilies IA and IB, this domain consists of an alpha-helical bundle. It was necessary to model these two subfamilies separately, breaking them at a an apparent phylogenetic bifurcation, so that the resulting model(s) are not so broadly defined that members of subfamily III (which lack the variable domain) are included. Subfamily IA includes the enzyme phosphoserine phosphatase (TIGR00338) as well as three hypothetical equivalogs. Many members of these hypothetical equivalogs have been annotated as PSPase-like or PSPase-family proteins. In particular, the hypothetical equivalog which appears to be most closely related to PSPase contains only Archaea (while TIGR00338 contains only eukaryotes and bacteria) of which some are annotated as PSPases. Although this is a reasonable conjecture, none of these sequences has sufficient evidence for this assignment. If such should be found, this model should be retired while the PSPase model should be broadened to include these sequences. [Unknown function, Enzymes of unknown specificity]

3-deoxy-D-manno-octulosonate 8-phosphate phosphatase, YrbI family; This family of proteins is a member of the IIIA subfamily of the haloacid dehalogenase (HAD) superfamily of hydrolases. All characterized members of this subfamily (TIGR01662) and most characterized members of the HAD superfamily are phosphatases. HAD superfamily phosphatases contain active site residues in several conserved catalytic motifs, all of which are found conserved here. One member of this family, the YrbI protein from H. influenzae has been cloned, expressed, purified and found to be an active 3-deoxy-D-manno-octulosonate 8-phosphate phosphatase. Furthermore, its crystal structure has been determined. This family consists of sequences from beta, gamma and epsilon proteobacteria, Aquifex, Fusobacterium, Porphyromonas and Methanosarcina. The Methanosarcina sequence is distinctive in that it is linked to an N-terminal cytidylyltransferase domain (pfam02348) and is annotated as acylneuraminate cytidylyltransferase. This may give some clue as the function of these phosphatases. Several eukaryotic sequences scoring between trusted and noise are also closely related to this function such as the CMP-N-acetylneuraminic acid synthetase from mouse, but in these cases the phosphatase domain is clearly inactive as many of the active site residues are not conserved.

Cof subfamily of IIB subfamily of haloacid dehalogenase superfamily; This subfamily of sequences falls within the Class-IIB subfamily (TIGR01484) of the Haloacid Dehalogenase superfamily of aspartate-nucleophile hydrolases. The use of the name "Cof" as an identifier here is arbitrary and refers to the E. coli Cof protein. This subfamily is notable for the large number of recent paralogs in many species. Listeria, for instance, has 12, Clostridium, Lactococcus and Streptococcus pneumoniae have 8 each, Enterococcus and Salmonella have 7 each, and Bacillus subtilus, Mycoplasma, Staphylococcus and E. coli have 6 each. This high degree of gene duplication is limited to the gamma proteobacteria and low-GC gram positive lineages. The profusion of genes in this subfamily is not coupled with a high degree of divergence, so it is impossible to determine an accurate phylogeny at the equivalog level. Considering the relationship of this subfamily to the other known members of the HAD-IIB subfamily (TIGR01484), sucrose and trehalose phosphatases and phosphomannomutase, it seems a reasonable hypothesis that these enzymes act on phosphorylated sugars. Possibly the diversification of genes in this subfamily represents the diverse sugars and polysaccharides that various bacteria find in their biological niches. The members of this subfamily are restricted almost exclusively to bacteria (one sequences from S. pombe scores above trusted, while another is between trusted and noise). It is notable that no archaea are found in this group, the closest relations to the archaea found here being two Deinococcus sequences. [Unknown function, Enzymes of unknown specificity]

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
Retrieve proteins that contain one or more of the domains present in the query sequence, using the Conserved Domain Architecture Retrieval Tool
(CDART).
