CC -!- FUNCTION: Nucleotidase with a broad substrate specificity as it can
CC dephosphorylate various ribo- and deoxyribonucleoside 5'-monophosphates
CC and ribonucleoside 3'-monophosphates with highest affinity to 3'-AMP.
CC Also hydrolyzes polyphosphate (exopolyphosphatase activity) with the
CC preference for short-chain-length substrates (P20-25). Might be
CC involved in the regulation of dNTP and NTP pools, and in the turnover
CC of 3'-mononucleotides produced by numerous intracellular RNases (T1,
CC T2, and F) during the degradation of various RNAs. {ECO:0000255|HAMAP-
