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
