haloacid dehalogenase superfamily, subfamily IA, variant 3 with third motif having DD or ED; This model represents part of one structural subfamily of the Haloacid Dehalogenase (HAD) superfamily of aspartate-nucleophile hydrolases. The superfamily is defined by the presence of three short catalytic motifs. The subfamilies are defined based on the location and the observed or predicted fold of a so-called "capping domain", or the absence of such a domain. Subfamily I consists of sequences in which the capping domain is found in between the first and second catalytic motifs. Subfamily II consists of sequences in which the capping domain is found between the second and third motifs. Subfamily III sequences have no capping domain in either of these positions. The Subfamily IA and IB capping domains are predicted by PSI-PRED to consist of an alpha helical bundle. Subfamily I encompasses such a wide region of sequence space (the sequences are highly divergent) that representing it with a single model is impossible, resulting in an overly broad description which allows in many unrelated sequences. Subfamily IA and IB are separated based on an aparrent phylogenetic bifurcation. Subfamily IA is still too broad to model, but cannot be further subdivided into large chunks based on phylogenetic trees. Of the three motifs defining the HAD superfamily, the third has three variant forms: (1) hhhhsDxxx(x)D, (2) hhhhssxxx(x)D and (3) hhhhDDxxx(x)s where _s_ refers to a small amino acid and _h_ to a hydrophobic one. All three of these variants are found in subfamily IA. Individual models were made based on seeds exhibiting only one of the variants each. Variant 3 (this model) is found in the enzymes beta-phosphoglucomutase (TIGR01990) and deoxyglucose-6-phosphatase, while many other enzymes of subfamily IA exhibit this variant as well as variant 1 (TIGR01549). These three variant models were created with the knowledge that there will be overlap among them - this is by design and serves the purpose of eliminating the overlap with models of more distantly related HAD subfamilies caused by an overly broad single model.

haloacid dehalogenase-like hydrolase; This family is structurally different from the alpha/beta hydrolase family (pfam00561). This family includes L-2-haloacid dehalogenase, epoxide hydrolases and phosphatases. The structure of the family consists of two domains. One is an inserted four helix bundle, which is the least well conserved region of the alignment, between residues 16 and 96 of Swiss:P24069. The rest of the fold is composed of the core alpha/beta domain. Those members with the characteriztic DxD triad at the N-terminus are probably phosphatidylglycerolphosphate (PGP) phosphatases involved in cardiolipin biosynthesis in the mitochondria.

epoxide hydrolase N-terminal domain-like phosphatase; This model represents a small clade of sequences including C. elegans and mammalian sequences as well as a small number of bacteria. In eukaryotes, this domain exists as an N-terminal fusion to the soluble epoxide hydrolase enzyme and has recently been shown to be an active phosphatase, although the nature of the biological substrate is unclear. These appear to be members of the haloacid dehalogenase (HAD) superfamily of aspartate-nucleophile hydrolases by general homology and the conservation of all of the recognized catalytic motifs (although the first motif is unusual in the replacement of the more common aspartate with glycine...). The variable domain is found in between motifs 1 and 2, indicating membership in subfamily I and phylogeny and prediction of the alpha helical nature of the variable domain (by PSI-PRED) indicate membership in subfamily IA.

Haloacid dehalogenase-like hydrolases; The haloacid dehalogenase-like (HAD) superfamily includes L-2-haloacid dehalogenase, epoxide hydrolase, phosphoserine phosphatase, phosphomannomutase, phosphoglycolate phosphatase, P-type ATPase, and many others. This superfamily includes a variety of enzymes that catalyze the cleavage of substrate C-Cl, P-C, and P-OP bonds via nucleophilic substitution pathways. All of which use a nucleophilic aspartate in their phosphoryl transfer reaction. They catalyze nucleophilic substitution reactions at phosphorus or carbon centers, using a conserved Asp carboxylate in covalent catalysis. All members possess a highly conserved alpha/beta core domain, and many also possess a small cap domain, the fold and function of which is variable. Members of this superfamily are sometimes referred to as belonging to the DDDD superfamily of phosphohydrolases.

L-2-haloacid dehalogenase; L-2-Haloacid dehalogenase catalyzes the hydrolytic dehalogenation of L-2-haloacids to produce the corresponding D-2-hydroxyacids with an inversion of the C2-configuration. 2-haloacid dehalogenases are of interest for their potential to degrade recalcitrant halogenated environmental pollutants and their use in the synthesis of industrial chemicals. This family belongs to the haloacid dehalogenase-like (HAD) hydrolases, a large superfamily of diverse enzymes that catalyze carbon or phosphoryl group transfer reactions on a range of substrates, using an active site aspartate in nucleophilic catalysis. Members of this superfamily include 2-L-haloalkanoic acid dehalogenase, azetidine hydrolase, phosphonoacetaldehyde hydrolase, phosphoserine phosphatase, phosphomannomutase, P-type ATPases and many others. HAD hydrolases are found in all three kingdoms of life, and most genomes are predicted to contain multiple HAD-like proteins. Members possess a highly conserved alpha/beta core domain, and many also possess a small cap domain, the fold and function of which is variable. HAD hydrolases are sometimes referred to as belonging to the DDDD superfamily of phosphohydrolases.

uncharacterized family of the haloacid dehalogenase-like superfamily, similar to uncharacterized Drosophila melanogaster rhythmically expressed gene 2 protein and human haloacid dehalogenase-like hydrolase domain-containing protein 3; The haloacid dehalogenase-like (HAD) hydrolases are a large superfamily of diverse enzymes that catalyze carbon or phosphoryl group transfer reactions on a range of substrates, using an active site aspartate in nucleophilic catalysis. Members include 2-L-haloalkanoic acid dehalogenase (C-Cl bond hydrolysis), azetidine hydrolase (C-N bond hydrolysis); phosphonoacetaldehyde hydrolase (C-P bond hydrolysis), phosphoserine phosphatase and phosphomannomutase (CO-P bond hydrolysis), P-type ATPases (PO-P bond hydrolysis) and many others. Members are found in all three kingdoms of life, and most genomes are predicted to contain multiple HAD-like proteins. Members possess a highly conserved alpha/beta core domain, and many also possess a small cap domain, the fold and function of which is variable. HAD hydrolases are sometimes referred to as belonging to the DDDD superfamily of phosphohydrolases.

HAD-superfamily hydrolase, subfamily IIIA; This subfamily falls within the Haloacid Dehalogenase (HAD) superfamily of aspartate-nucleophile hydrolases. The Class III subfamilies are characterized by the lack of any domains located between either between the first and second conserved catalytic motifs (as in the Class I subfamilies, TIGR01493, TIGR01509, TIGR01488 and TIGR01494) or between the second and third conserved catalytic motifs (as in the Class II subfamilies, TIGR01460 and TIGR01484) of the superfamily domain. The IIIA subfamily contains five major clades: histidinol-phosphatase (TIGR01261) and histidinol-phosphatase-related protein (TIGR00213) which together form a subfamily (TIGR01656), DNA 3'-phosphatase (TIGR01663, TIGR01664), YqeG (TIGR01668) and YrbI (TIGR01670). In the case of histidinol phosphatase and PNK-3'-phosphatase, this model represents a domain of a bifunctional system. In the histidinol phosphatase HisB, a C-terminal domain is an imidazoleglycerol-phosphate dehydratase which catalyzes a related step in histidine biosynthesis. In PNK-3'-phosphatase, N- and C-terminal domains constitute the polynucleotide kinase and DNA-binding components of the enzyme. [Unknown function, Enzymes of unknown specificity]
