Comments [?]

case <OC:Enterobacterales>
FUNCTIONNucleotidase 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 Reaction=a ribonucleoside 5'-phosphate + H2O = a ribonucleoside + phosphate; Xref=Rhea:RHEA:12484, ChEBI:CHEBI:15377, ChEBI:CHEBI:18254, ChEBI:CHEBI:43474, ChEBI:CHEBI:58043; EC=3.1.3.5;

Comments In some organisms, surE was originally annotated as an acid phosphatase (EC 3.1.3.2). Weird C-terminal sequence in TREPA; no obvious frameshift; not shown in alignment and not used in size range. There are divergent second copies of surE in NOSS1 (alr3139) and SYNY3 (sll1459).
