Identification
Name:Deoxyuridine
Description2'-Deoxyuridine is a naturally occurring nucleoside. It is similar in chemical structure to uridine, but without the 2'-hydroxyl group. It is considered to be an antimetabolite that is converted to deoxyuridine triphosphate during DNA synthesis.

Specific function:
Degradation of external UDP-glucose to uridine monophosphate and glucose-1-phosphate, which can then be used by the cell
Gene Name:
ushA
Uniprot ID:
P07024
Molecular weight:
60824
Reactions
UDP-sugar + H(2)O = UMP + alpha-D-aldose 1-phosphate.
A 5'-ribonucleotide + H(2)O = a ribonucleoside + phosphate.
General function:
Involved in transferase activity, transferring glycosyl groups
Specific function:
The enzymes which catalyze the reversible phosphorolysis of pyrimidine nucleosides are involved in the degradation of these compounds and in their utilization as carbon and energy sources, or in the rescue of pyrimidine bases for nucleotide synthesis
Gene Name:
deoA
Uniprot ID:

Reactions
Thymidine + phosphate = thymine + 2-deoxy-alpha-D-ribose 1-phosphate.
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 E.coli in stationary growth phase

(Polyphosphate)(n) + H(2)O = (polyphosphate)(n-1) + phosphate.
General function:
Involved in catalytic activity
Specific function:
Nucleotidase that shows high phosphatase activity toward three nucleoside 5'-monophosphates, UMP, dUMP, and dTMP, and very low activity against TDP, IMP, UDP, GMP, dGMP, AMP, dAMP, and 6- phosphogluconate. Is strictly specific to substrates with 5'- phosphates and shows no activity against nucleoside 2'- or 3'- monophosphates. Might be involved in the pyrimidine nucleotide substrate cycles

Molecular weight:
25950
Reactions
Purine nucleoside + phosphate = purine + alpha-D-ribose 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:
aphA
Uniprot ID:
P0AE22
Molecular weight:
26103
Reactions
A phosphate monoester + H(2)O = an alcohol + phosphate.
General function:
Involved in transferase activity, transferring pentosyl groups
Specific function:
Catalyzes the reversible phosphorylytic cleavage of uridine and deoxyuridine to uracil and ribose- or deoxyribose-1- phosphate. The produced molecules are then utilized as carbon and energy sources or in the rescue of pyrimidine bases for nucleotide synthesis
Gene Name:
udp
Uniprot ID:
P12758
Molecular weight:

Reactions
Uridine + phosphate = uracil + alpha-D-ribose 1-phosphate.
General function:
Involved in thymidine kinase activity
Specific function:
Phosphorylates both thymidine and deoxyuridine
Gene Name:
tdk
Uniprot ID:
P23331
Molecular weight:
23456
Reactions
ATP + thymidine = ADP + thymidine 5'-phosphate.
General function:
Involved in catalytic activity
Specific function:
Nucleotidase that shows strict specificity toward deoxyribonucleoside 5'-monophosphates and does not dephosphorylate 5'-ribonucleotides or ribonucleoside 3'-monophosphates. Might be involved in the regulation of all dNTP pools in E.coli
Gene Name:
yfbR
Uniprot ID:
P76491
Molecular weight:
