Protein namesi

  • Recommended name:
    5'/3'-nucleotidase SurE (EC:3.1.3.5, EC:3.1.3.6)
    Alternative name(s):

    Nucleoside monophosphate phosphohydrolase
  • Recommended name:

Subcellular locationi

Cofactori

Catalytic activityi

  • (Polyphosphate)(n) + H2O = (polyphosphate)(n-1) + phosphate.
  • A 3'-ribonucleotide + H2O = a ribonucleoside + phosphate.
  • A 5'-ribonucleotide + H2O = a ribonucleoside + phosphate.
  • A 5'-ribonucleotide + H2O = a ribonucleoside + phosphate.

Functioni

  • 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.
  • Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates.
