Identification
Name:Deoxyinosine
Description:Deoxyinosine is a nucleoside that is formed when hypoxanthine is attached to a deoxyribose ring (also known as a ribofuranose) via a beta-N9-glycosidic bond. Deoxyinosine is found in DNA while Inosine is found in RNA. Inosine is a nucleic acid important for RNA editing. Adenosine deaminase (ADA) catalyzes the conversion of adenosine and deoxyadenosine to inosine and deoxyinosine, respectively.

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:
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 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
