Descriptions

Application

Phosphodiesterase (PDE) is any enzyme that is used to breaks phosphodiester bonds. It is a membrane-bound glycoprotein that is used to catalyze the hydrolysis of various nucleotide polyphosphates. Phosphodiesterase I is used in phosphodiesterase activation assays to hydrolyze AMP. Product P3243 is from Crotalus adamanteus venom and is purified. Product P3243 has been used to hydrolyze tRNA with wyosine derivatives into mononucleosides.

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.

Preparation Note

Purified via the method of Williams, et al. and further treated to inactivate contaminating 5?-nucleotidase activity.

Unit Definition
