Protein existence	Inferred from homology

General annotation (Comments)

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 By similarity. HAMAP-Rule MF_00060
Catalytic activity	A 5'-ribonucleotide + H2O = a ribonucleoside + phosphate. HAMAP-Rule MF_00060 A 3'-ribonucleotide + H2O = a ribonucleoside + phosphate. HAMAP-Rule MF_00060 (Polyphosphate)(n) + H2O = (polyphosphate)(n-1) + phosphate. HAMAP-Rule MF_00060
Cofactor	Binds 1 divalent metal cation per subunit By similarity.
Subcellular location	Cytoplasm Potential HAMAP-Rule MF_00060.
Sequence similarities	Belongs to the SurE nucleotidase family.
Sequence caution	The sequence AAN81760.1 differs from that shown. Reason: Erroneous initiation.
