Haloacid Dehalogenase-like Hydrolases; The haloacid dehalogenase (HAD) superfamily includes carbon and phosphorus hydrolases such as 2-haloalkonoate dehalogenase, epoxide hydrolase, phosphoserine phosphatase, phosphomannomutase, phosphoglycolate phosphatase, P-type ATPase, among others. These proteins catalyze nucleophilic substitution reactions at phosphorus or carbon centers, using a conserved Asp carboxylate in covalent catalysis. All members possess a conserve alpha/beta core domain, and many also possess a small cap domain, with varying folds and functions.

alpha-subunit of Na(+)/K(+)-ATPases and of gastric H(+)/K(+)-ATPase, similar to the human Na(+)/K(+)-ATPase alpha subunits 1-4; This subfamily includes the alpha subunit of Na(+)/K(+)-ATPase a heteromeric transmembrane protein composed of an alpha- and beta-subunit and an optional third subunit belonging to the FXYD proteins which are more tissue specific regulatory subunits of the enzyme. The alpha-subunit is the catalytic subunit responsible for transport activities of the enzyme. 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. This subfamily also includes Oreochromis mossambicus (tilapia) Na(+)/K(+)-ATPase alpha 1 and alpha 3 subunits, and gastric H(+)/K(+)-ATPase which exchanges hydronium ion with potassium and is responsible for gastric acid secretion. Gastric H(+)/K(+)-ATPase is an alpha,beta-heterodimeric enzyme. 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.

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.

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.

golgi-associated secretory pathway Ca(2+) transport ATPases, similar to human ATPase secretory pathway Ca(2+) transporting 1/hSPCA1 and Saccharomyces cerevisiae Ca(2+)/Mn(2+)-transporting P-type ATPase, Pmr1p; SPCAs are Ca(2+) pumps important for the golgi-associated secretion pathway, in addition some function as Mn(2+) pumps in Mn(2+) detoxification. Saccharomyces cerevisiae Pmr1p is a high affinity Ca(2+)/Mn(2+) ATPase which transports Ca(2+) and Mn(2+) from the cytoplasm into the Golgi. Pmr1p also contributes to Cd(2+) detoxification. This subfamily includes human SPCA1 and SPCA2, encoded by the ATP2C1 and ATP2C2 genes; autosomal dominant Hailey-Hailey disease is caused by mutations in the human ATP2C1 gene. It also includes Strongylocentrotus purpuratus testis secretory pathway calcium transporting ATPase SPCA which plays an important role in fertilization. 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.

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. The activity of SERCA is regulated by two small membrane proteins called phospholamban and sarcolipin. 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.

This model describes the clade of fungal P-type ATPases responsible for potassium and sodium efflux. The degree to which these pumps show preference for sodium or potassium varies. This group of ATPases has been classified by phylogentic analysis as type IID. The Leishmania sequence (GP|3192903), which falls between trusted and noise in this model, may very well turn out to be an active potassium pump.
