Names

Accepted name:
2',3'-cyclic-nucleotide 3'-phosphodiesterase
Other names:

2',3'-cyclic nucleotide 3'-phosphohydrolase
2',3'-cyclic nucleotide phosphohydrolase
2':3'-CNMP-3'-ase
2':3'-cyclic nucleotide 3'-phosphodiesterase
CNPase
cyclic 2',3'-nucleotide 3'-phosphodiesterase
cyclic 2',3'-nucleotide phosphodiesterase
cyclic-CMP phosphodiesterase
Systematic name:

Reactions

Comments:

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.
