Uses
The product has been used in the characterization of polynucleotide chain length, base composition, and identity of terminal nucleotide. The enzyme has also been used in excision of pyridyloxobutyl (POB) base adducts from DNA. Furthermore, it has been used along with micrococcal endonuclease to hydrolyze purified DNA to 3 -nucleoside monophosphates.
General Description
Phosphodiesterase (PDE) II belong to the PDE superfamily and includes subtypes from one to 11. They exists as a dimer and comprise a N-terminal regulatory domain, C-terminal prenylated domain and a Zn
2+ containing catalytic domain. The bovine spleen PDE2 corresponds to a molecular weight of 65 kDa. It requires divalent cations for its enzymatic activity and has an optimum pH of 7.5.
Biochem/physiol Actions
Phosphodiesterase (PDE) breaks phosphodiester bonds. 3-Isobutyl-methylxanthine (IBMX) is a potential PDE2 inhibitor.
