IUBMB Enzyme Nomenclature


Accepted name: 3',5'-cyclic-AMP phosphodiesterase

Reaction: adenosine 3',5'-cyclic phosphate + H2O = AMP

Glossary: AMP = adenosine 5'-phosphate

Other name(s): cAMP-specific phosphodiesterase; cAMP-specific PDE; PDE1; PDE2A; PDE2B; PDE4; PDE7; PDE8; PDEB1; PDEB2

Systematic name: 3',5'-cyclic-AMP 5'-nucleotidohydrolase

Comments: Requires Mg2+ or Mn2+ for activity [2]. This enzyme is specific for 3',5'-cAMP and does not hydrolyse other nucleoside 3',5'-cyclic phosphates such as cGMP (c.f. EC, 3"-cyclic-nucleotide phosphodiesterase and EC, 3',5'-cyclic-GMP phosphodiesterase). It is involved in modulation of the levels of cAMP, which is a mediator in the processes of cell transformation and proliferation [3].
