Class III cyclic nucleotide phosphodiesterase (cNMP PDE); Hydrolyzes cAMP to 5'-AMP. Plays an important regulatory role in modulating the intracellular concentration of cAMP, thereby influencing cAMP-dependent processes. Can also hydrolyze cGMP, p- nitrophenyl phosphate (pNPP), bis-(p-nitrophenyl phosphate) (bis(pNPP)), p-nitrophenyl phenylphosphonate (pNPPP) and 2',3'-cAMP. May play a role in pathogenicity, not only by hydrolyzing cAMP, but also by altering properties of the cell wall.
