Description

General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been used as enzyme for alternative energy. For more information see the Enzymes for Alternative Energy Research.

Substrate Specificity

4 hydroquinone + O₂ = 4 benzosemiquinone + 2 H₂O

Application

Laccase is polyphenol oxidase found in many plants, fungi and microorganisms. Laccases may be useful in enzymatic biofuel systems, teeth whitening, textile dyeing, and in other applications that require the removal of oxygen .

Biochem/physiol Actions

Laccase is a blue copper oxidase that reduces molecular oxygen to water. Laccase oxidizes polyphenols, methoxy-substituted phenols and diamines, but not tyrosine. Oxidation by laccase is an one-electron reaction that generates a free radical .

Other Notes

1 U corresponds to the amount of enzyme which converts 1 μmol catechol per minute at pH 6.0 and 25°C
