Catalase de Micrococcus lysodeikticus, solution, brun foncé

Non disponible en dehors du Royaume-Uni et de l'Irlande

Application

Catalase from Micrococcus lysodeikticus has been used to eliminate excess of hydrogen peroxide production during sugar analog synthesis by in vitro biocatalytic cascade. It has also been used as a standard to evaluate oxidative stress by indirectly measuring catalytic activity.

Biochem/physiol Actions

Catalase rapidly converts hydrogen peroxide to oxygen and water. It exhibits antioxidant activity and elicits a defense mechanism against reactive oxygen species (ROS). Catalase plays a role in neutralizing noxious hydrogen peroxide in nature as well as in various industries such as textile, pharma, and dairy. Micrococcus lysodeikticus catalase is a haem-containing protein.
