Descrizione generale

Chloroperoxidase (CPO) is a major heme-containing,[1] synthetic and versatile enzyme, obtained from Caldariomyces fumago.[2]

Applicazioni

A useful alternative to lactoperoxidase for 131I ion labeling studies, for bromination of proteins, and for 36Cl labeling of macromolecules in long-term isolation procedures.

Azioni biochim/fisiol

Chloroperoxidase (CPO) helps in the catalysis of oxidation reactions with the help of hydrogen peroxide.[2] It displays peroxidase, catalase and cytochrome P450-like functions. CPO also plays a role in catalyzing halogenation reactions.[1]

Definizione di unità

1 U corresponds to the amount of enzyme which converts 1 μmol of monochlorodimedone to dichlorodimedone per minute at pH 2.75 and 25 °C in the presence of KCl and H2O2.

Stato fisico

Supplied as a suspension in 0.1 M sodium phosphate pH 4.0.

Although in the absence of halide ion chloroperoxidase did not catalyze the ethylhydroperoxide (EHP)-supported oxidation of aminopyrine, in the presence of Br- or Cl-, chloroperoxidase did catalyze the oxidation of aminopyrine, generating the aminopyrine cation radical (AP+). The initial rate

Azide is a well-known inhibitor of heme-enzymes. Herein, we report the counter-intuitive observation that at some concentration regimes, incorporation of azide in the reaction medium enhances chloroperoxidase (CPO, a heme-enzyme) mediated one-electron abstractions from several substrates.

Questions

1–2 of 2 Questions  
  1. I would like to know the weight of enzyme in 25810-1ML-F. Thanks!

    1 answer
    1. This solution is prepared based on the unit activity. The protein content is not determined, therefore the weight of the enzyme is not available. Should this information be required, the end user would have to determine the protein concentration by Bradford Assay.

  2. Kann ich die CfuCPO-probe auch in Gefrierschrank lagern?

    1 answer
    1. Recommended storage temperature of the product is 2-8°C. Any potential damage resulting from the freeze/thaw process has not been investigated. It is not advised to store the product in the freezer.
