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.

Other Notes

One Unit hydrolyzes one μmole of p-nitrophenyl thymidine-5-phosphate per minute at 25 °C, pH 8.9

Preparation Note

For testing purposes, PDE I is reconstituted in cold deionized water at 0.1 - 0,2 un/mL.
Purified via the method of Williams, et al. and further treated to inactivate contaminating 5′-nucleotidase activity.

The metazoan second messenger 2'3'-cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) is a cyclic dinucleotide (CDN) that induces secretion of type I interferons and activates the immune system and has thus attracted significant interest as a vaccine adjuvant or immunotherapeutic.

Protocols

Enzymatic Assay of 5’-Nucleotidase

To measure 5′-nucleotidase activity, this procedure uses adenosine 5’-monophosphate and a color reagent to create a standard curve for determining the micromoles of phosphorus liberated.
