General function:
Involved in GMP synthase (glutamine-hydrolyzing) activity
Specific function:
Catalyzes the synthesis of GMP from XMP
Gene Name:
Locus Tag:
Molecular weight:
58 kDa
ATP + xanthosine 5'-phosphate + L-glutamine + H(2)O = AMP + diphosphate + GMP + L-glutamate.
General function:
Involved in hydrolase activity
Specific function:
Nucleotidase with a broad substrate specificity as it can dephosphorylate various ribo- and deoxyribonucleoside 5'- monophosphates and ribonucleoside 3'-monophosphates with highest affinity to 3'-AMP. Also hydrolyzes polyphosphate (exopolyphosphatase activity) with the preference for short-chain- length substrates (P20-25). Might be involved in the regulation of dNTP and NTP pools, and in the turnover of 3'-mononucleotides produced by numerous intracellular RNases (T1, T2, and F) during the degradation of various RNAs. Also plays a significant physiological role in stress-response and is required for the survival of Pseudomonas aeruginosa in stationary growth phase
Gene Name:
Locus Tag:
Molecular weight:
26.4 kDa
A 5'-ribonucleotide + H(2)O = a ribonucleoside + phosphate.
A 3'-ribonucleotide + H(2)O = a ribonucleoside + phosphate.
(Polyphosphate)(n) + H(2)O = (polyphosphate)(n-1) + phosphate.
General function:
Involved in acid phosphatase activity
Specific function:
Dephosphorylates several organic phosphomonoesters and catalyzes the transfer of low-energy phosphate groups from phosphomonoesters to hydroxyl groups of various organic compounds. Preferentially acts on aryl phosphoesters. Might function as a broad-spectrum dephosphorylating enzyme able to scavenge both 3'- and 5'-nucleotides and also additional organic phosphomonoesters
Gene Name:
Locus Tag:
Molecular weight:
38 kDa
A phosphate monoester + H(2)O = an alcohol + phosphate.
General function:
Involved in nucleoside-triphosphate diphosphatase activity
Specific function:
Specific function unknown
Gene Name:
Locus Tag:
Molecular weight:
31.2 kDa
ATP + H(2)O = AMP + diphosphate.
General function:
Involved in hydrolase activity
Specific function:
Hydrolyzes O6 atom-containing purine bases deoxyinosine triphosphate (dITP) and xanthosine triphosphate (XTP) as well as 2'-deoxy-N-6-hydroxylaminopurine triposphate (dHAPTP) to nucleotide monophosphate and pyrophosphate. Probably excludes non- standard purines from DNA precursor pool, preventing thus incorporation into DNA and avoiding chromosomal lesions
Gene Name:
Locus Tag:
Molecular weight:
21.2 kDa
A nucleoside triphosphate + H(2)O = a nucleotide + diphosphate.
General function:
Involved in protein binding
Specific function:
Essential for recycling GMP and indirectly, cGMP
Gene Name:
Locus Tag:
Molecular weight:
23.1 kDa
General function:
Involved in adenine phosphoribosyltransferase activity
Specific function:
Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis
Gene Name:
Locus Tag:
Molecular weight:
19.8 kDa
AMP + diphosphate = adenine + 5-phospho-alpha-D-ribose 1-diphosphate.
General function:
Replication, recombination and repair
Specific function:
Involved in the GO system responsible for removing an oxidatively damaged form of guanine (7,8-dihydro-8-oxoguanine) from DNA and the nucleotide pool. 8-oxo-dGTP is inserted opposite dA and dC residues of template DNA with almost equal efficiency thus leading to A.T to G.C transversions. MutT specifically degrades 8-oxo-dGTP to the monophosphate
Gene Name:
Locus Tag:
Molecular weight:
34 kDa
8-oxo-dGTP + H(2)O = 8-oxo-dGMP + diphosphate.
