Reactions
A phosphate monoester + H(2)O = an alcohol + phosphate.
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:

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:
This bifunctional enzyme catalyzes two consecutive reactions during ribonucleic acid degradation. Converts a 2',3'- cyclic nucleotide to a 3'-nucleotide and then the 3'-nucleotide to the corresponding nucleoside and phosphate
Gene Name:
cpdB
Uniprot ID:
P08331
Molecular weight:
70832
Reactions
Nucleoside 2',3'-cyclic phosphate + H(2)O = nucleoside 3'-phosphate.
A 3'-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
