Catalase from Micrococcus lysodeikticus, solution, dark brown

Not available outside of the UK & Ireland.

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.
