Catalyzes the release of inorganic phosphate from 2',3'-cyclic nucleotides through consecutive 2',3'-phosphodiesterase and 3'- (or 2') nucleotidase activities. Also possesses a 5'-nucleotidase activity. Does not catalyze the release of inorganic phosphate from 3',5'-cyclic nucleotides. Probably plays a role in the cellular reprocessing of nucleotides present in the medium, under conditions of phosphate shortage. a nucleoside 2',3'-cyclic phosphate + H2O = a nucleoside 3'-phosphate + H(+) a ribonucleoside 3'-phosphate + H2O = a ribonucleoside + phosphate a ribonucleoside 5'-phosphate + H2O = a ribonucleoside + phosphate The 2',3'-cyclic phosphodiesterase activity is higher than that of the 5'-nucleotidase with the four major nucleotides used as substrates. Anchored to the cell wall by sortase SrtD. Expression is induced in response to phosphate starvation in a PhoR-dependent manner. The N-terminal region (amino acids 35-623) is able to catalyze the release of phosphate from 2',3'-cyclic nucleotides, but not from 5'-nucleotides. Belongs to the 5'-nucleotidase family.
