cyclic 2',3'-nucleotide 3'-phosphodiesterase;
cyclic 2',3'-nucleotide phosphodiesterase;
2',3'-cyclic nucleoside monophosphate phosphodiesterase;
2',3'-cyclic nucleotide 3'-phosphohydrolase;
CNPase;
2',3'-cyclic nucleotide phosphohydrolase;
2':3'-cyclic nucleotide 3'-phosphodiesterase;
2':3'-CNMP-3'-ase
Class

Phosphoric-diester hydrolases
BRITE hierarchy
Sysname
nucleoside-2',3'-cyclic-phosphate 2'-nucleotidohydrolase
Reaction(IUBMB)
nucleoside 2',3'-cyclic phosphate + H2O = nucleoside 2'-phosphate [RN:R03422]
Reaction(KEGG)
Substrate
nucleoside 2',3'-cyclic phosphate [CPD:C01240];
H2O [CPD:C00001]
Product
nucleoside 2'-phosphate [CPD:C03418]
Comment
The brain enzyme acts on 2',3'-cyclic AMP more rapidly than on the UMP or CMP derivatives. An enzyme from liver acts on 2',3'-cyclic CMP more rapidly than on the purine derivatives; it also hydrolyses the corresponding 3',5'-cyclic phosphates, but more slowly. This latter enzyme has been called cyclic-CMP phosphodiesterase.
