Function
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.
Catalytic activity
- [phosphate](n) + H2O = [phosphate](n-1) + phosphate + H+
[phosphate](n) RHEA-COMP:9859 + CHEBI:15377 = [phosphate](n-1) RHEA-COMP:14279 + CHEBI:43474 + CHEBI:15378
Cofactor
Note: Binds 1 divalent metal cation per subunit.
