General description
Research area: Cell Signaling
Catalase (CAT) is an antioxidant enzyme, encoded by the CAT gene family. The enzyme is ubiquitously expressed in most of the aerobic organisms.[1]
Catalase (CAT) is an antioxidant enzyme, encoded by the CAT gene family. The enzyme is ubiquitously expressed in most of the aerobic organisms.[1]
Application
Biochem/physiol Actions
Catalase rapidly converts hydrogen peroxide to oxygen and water.[6] 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.[7] Micrococcus lysodeikticus catalase is a heme-containing protein.[5]Catalase, along with various key cellular systems involved in hydrogen peroxide (H2O2) processing, plays a key role in regulating cellular redox balance and aids in cellular and intercellular signaling.[8]
Unit Definition
1 U corresponds to the amount of enzyme which decomposes 1 μmol H2O2 per minute at pH 7.0 and 25 °C
