1-246 3.97e-162

haloacid dehalogenase (HAD)-like 5'-nucleotidases similar to human cytosolic IIIA and IIIB; 5'-nucleotidases dephosphorylate nucleoside 5prime-monophosphates. This family includes human 5'-nucleotidase, cytosolic IIIA (cN-IIIA, previously called cN-III; NT5C3A) the main pyrimidine 5'-nucleotidase in erythrocytes which dephosphorylates the pyrimidine nucleotides CMP, UMP, TMP, and the purine 7-methylguanosine monophosphate (m7GM), and possesses phosphotransferase activity. It also includes human 5'-nucleotidase, cytosolic IIIB (cN-IIIB; NT5C3B) which has a strong preference for m7GMP, dephosphorylates CMP and UMP and, with significantly lower efficiency, GMP and AMP, and can also act as a phosphotransferase. 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.

1-245 2.30e-113

haloacid dehalogenase superfamily, subfamily IE hydrolase, TIGR01544; This model represents a small group of metazoan sequences. The sequences from mouse are annotated as Pyrimidine 5'-nucleotidases, aparrently in reference to HSPC233, the human homolog. However, no such annotation can currently be found for this gene. This group of sequences was found during searches for members of the haloacid dehalogenase (HAD) superfamily. All of the conserved catalytic motifs are found. The placement of the variable domain between motifs 1 and 2 indicates membership in subfamily I of the superfamily, but these sequences are sufficiently different from any of the branches (IA, TIGR01493, TIGR01509, TIGR01549; IB, TIGR01488; IC, TIGR01494; ID, TIGR01658; IF TIGR01545) of that subfamily as to constitute a separate branch to now be called IE. Considering that the closest identifiable hit outside of the noise range is to a phosphoserine phosphatase, this group may be considered to be most closely allied to subfamily IB.

1-245 2.30e-113

haloacid dehalogenase superfamily, subfamily IE hydrolase, TIGR01544; This model represents a small group of metazoan sequences. The sequences from mouse are annotated as Pyrimidine 5'-nucleotidases, aparrently in reference to HSPC233, the human homolog. However, no such annotation can currently be found for this gene. This group of sequences was found during searches for members of the haloacid dehalogenase (HAD) superfamily. All of the conserved catalytic motifs are found. The placement of the variable domain between motifs 1 and 2 indicates membership in subfamily I of the superfamily, but these sequences are sufficiently different from any of the branches (IA, TIGR01493, TIGR01509, TIGR01549; IB, TIGR01488; IC, TIGR01494; ID, TIGR01658; IF TIGR01545) of that subfamily as to constitute a separate branch to now be called IE. Considering that the closest identifiable hit outside of the noise range is to a phosphoserine phosphatase, this group may be considered to be most closely allied to subfamily IB.

86-233 5.10e-08

phosphatase, similar to Bacillus subtilis MtnX; belongs to the haloacid dehalogenase-like superfamily; Bacillus subtilis recycles two toxic byproducts of polyamine metabolism, methylthioadenosine and methylthioribose, into methionine by a salvage pathway. The sixth reaction in this pathway is catalyzed by B. subtilis MtnX: the dephosphorylation of 2- hydroxy-3-keto-5-methylthiopentenyl-1-phosphate (HKMTP- 1-P) into 1,2-dihydroxy-3-keto-5-methylthiopentene. The hydrolysis of HK-MTP-1-P is a two-step mechanism involving the formation of a transiently phosphorylated aspartyl intermediate. Members of this family belong 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.

79-192 2.99e-05

phosphoserine phosphatase eukaryotic-like, similar to human phosphoserine phosphatase; Human PSP, EC 3.1.3.3, catalyzes the third and final of the L-serine biosynthesis pathway, the Mg2+-dependent hydrolysis of phospho-L-serine to L-serine and inorganic phosphate, L-serine is a precursor for the biosynthesis of glycine. HPSP regulates the levels of glycine and D-serine (converted from L-serine), the putative co-agonists for the glycine site of the NMDA receptor in the brain. Plant 3-PSP catalyzes the conversion of 3-phosphoserine to serine in the last step of the plastidic pathway of serine biosynthesis. 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.

69-195 5.79e-04

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]
