Reaction: nucleoside 2',3'-cyclic phosphate + H2O = nucleoside 3'-phosphate
Other name(s): ribonucleoside 2',3'-cyclic phosphate diesterase; 2',3 '-cyclic AMP phosphodiesterase; 2',3'-cyclic nucleotidase; cyclic 2',3'-nucleotide 2'-phosphodiesterase; cyclic 2',3'-nucleotide phosphodiesterase; 2',3'-cyclic nucleoside monophosphate phosphodiesterase; 2',3'-cyclic AMP 2'-phosphohydrolase; cyclic phosphodiesterase:3'-nucleotidase; 2',3'-cyclic nucleotide phosphohydrolase; 2':3'-cyclic phosphodiesterase; 2':3'-cyclic nucleotide phosphodiesterase:3'-nucleotidase
Systematic name: nucleoside-2',3'-cyclic-phosphate 3'-nucleotidohydrolase
Comments: Also hydrolyses 3'-nucleoside monophosphates and bis-4-nitrophenyl phosphate, but not 3'-deoxynucleotides. Similar reactions are carried out by EC 18.104.22.168 (ribonuclease T1) and EC 22.214.171.124 (pancreatic ribonuclease).
