General description

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

Application

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.

Biochem/physiol Actions

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]

Physical form

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

Other Notes

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.

Chloroperoxidase-catalyzed oxidation of aminopyrine.

H Sayo et al.

Chemical & pharmaceutical bulletin, 37(12), 3347-3350 (1989-12-01)

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

Heme peroxidases are subject to a mechanism-based oxidative inactivation. During the catalytic cycle, the heme group is activated to form highly oxidizing species, which may extract electrons from the protein itself. In this work, we analyze changes in residues prone

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

  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.
