Identification
Name: Guanosine
Description:Guanosine is a nucleoside comprising guanine attached to a ribose (ribofuranose) ring via a beta-N9-glycosidic bond. Guanosine can be phosphorylated to become GMP (guanosine monophosphate), cGMP (cyclic guanosine monophosphate), GDP (guanosine diphosphate) and GTP (guanosine triphosphate). (Wikipedia)

Enzymes

Protein Details
• Multifunctional protein surE
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:
surE
Locus Tag:
PA3625
Molecular weight:
26.4 kDa
Reactions
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.
Protein Details
• Class B acid phosphatase
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:
aphA
Locus Tag:
PA1409
Molecular weight:
38 kDa
Reactions
A phosphate monoester + H(2)O = an alcohol + phosphate.
Protein Details
• Deoxyguanosinetriphosphate triphosphohydrolase
General function:
Involved in magnesium ion binding
Specific function:
dGTPase preferentially hydrolyzes dGTP over the other canonical NTPs
Gene Name:
dgt
Locus Tag:
PA1124
Molecular weight:
56.7 kDa
Reactions
dGTP + H(2)O = deoxyguanosine + triphosphate.
