Identification
Name:Deoxycytidine
DescriptionDeoxycytidine is one of the principal nucleosides of DNA composed of cytosine and deoxyribose. A nucleoside consists of only a pentose sugar linked to a purine or pyrimidine base, without a phosphate group. When N1 is linked to the C1 of deoxyribose, deoxynucleosides and nucleotides are formed from cytosine and deoxyribose; deoxycytidine monophosphate (dCMP), deoxycytidine diphosphate (dCDP), deoxycytidine triphosphate (dCTP). CTP is the source of the cytidine in RNA (ribonucleic acid) and deoxycytidine triphosphate (dCTP) is the source of the deoxycytidine in DNA (deoxyribonucleic acid).

Enzymes

General function:
Involved in hydrolase activity
Specific function:
Degradation of external UDP-glucose to uridine monophosphate and glucose-1-phosphate, which can then be used by the cell
Gene Name:

Uniprot ID:
P07024
Molecular weight:

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 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

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
