Les peroxydases végétales de classe III

Abstract

Peroxidases are heme proteins involved in the oxidization of a large variety of substrates, through the reaction with hydrogen peroxide. Plant peroxidases are class III peroxidases, according to nomenclature. Primary and tertiary structure, as well as principles of reactions catalyzed by such peroxidases are discussed. Class III peroxidases are involved in different physiological functions, such as cell wall metabolism, hormonal metabolism, responses to abiotic stresses, and plant-microorganisms interactions. Biotechnological applications are presented. © 2004, Taylor & Francis Group, LLC.
