Application

Phosphodiesterase (PDE) is any enzyme that is used to breaks phosphodiester bonds. Phosphodiesterase I, product P4506 from western diamondback rattlesnake, is used in phosphodiesterase activation assays for calmodulin. It is added to hydrolyze AMP. It is a membrane-bound glycoprotein that is used to catalyze the hydrolysis of various nucleotide polyphosphates.

Phosphodiesterase I from Crotalus atrox (Western Diamondback Rattlesnake) has been used to analyse its effect on intracellular calcium concentration of neutrophils. It has also been used in combination with other enzymes to determine the activity of phosphatase enzyme.

Biochem/physiol Actions

Phosphodiesterase I breaks phosphodiester bonds and catalyzes the hydrolysis of various nucleotide polyphosphates. Phosphodiesterase I is released from eucaryotic plasma membranes by phosphatidylinositol-specific phospholipase C.
