Applicazioni

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[1].

Azioni biochim/fisiol

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.

Definizione di unità

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

Nota sulla preparazione

Purified via the method of Williams, et al.[2] and further treated to inactivate contaminating 5′-nucleotidase activity.

Ricostituzione

For testing purposes, PDE I is reconstituted in cold deionized water at 0.1 - 0,2 un/mL.

Protocolli

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.

Questions

1–2 of 2 Questions  
  1. 1. If I want to dissolve this venom what I can use distilled water or any buffer? And what is the storage temperature after reconstitution? 2. If I want to increase the efficiency of venom what I can use?

    1 answer
    1. For testing purposes, this product is reconstituted in cold deionized water at 0.1 - 0,2 un/mL. The solution stability and storage conditions have not been determined. The enzyme may also be dissolved in 0.11 M Tris HCl buffer, pH 8.9 with 0.11 M NaCl and 15 mM MgCl2 according to Worthington Manual, p. 310 (1993). Note that this material is not the raw venom, but the purified enzyme. The enzyme is purified via the method of Williams, et al. and further treated to inactivate contaminating 5′-nucleotidase activity.
