Peroxidase Isoenzymes from Horseradish Roots
The reactivity of histidine in horseradish peroxidase isoenzymes Al and C was determined by titrating with diazonium-lH-tetrazole. No exposed histidine residue was detected in the native isoenzymes. Upon removal of the heme prosthetic group, however, all three histidine residues became titratable. Studies with p-chloromercuribenzoate and 14C-iodoacetamide indicated that the 6 half-cystine resid...
متن کاملZo-peroxidase: Crystal structure and sequence of a highly-glycosylated peroxidase resistant to high concentrations of H2O2 from Japanese radish
Understanding Peroxidase (PRXs) enzymatic diversity and functional significance from a three-dimensional point of view is a key point for structural and mechanistic studies. In this context, Zo-peroxidase (ZoPrx) a member of the class III peroxidases and secreted by plants, differs from all previously described PRXs because of its remarkable catalytic stability in the presence of hydrogen perox...
متن کاملRegulation and function of ascorbate peroxidase isoenzymes.
Even under optimal conditions, many metabolic processes, including the chloroplastic, mitochondrial, and plasma membrane-linked electron transport systems of higher plants, produce active oxygen species (AOS). Furthermore, the imposition of biotic and abiotic stress conditions can give rise to excess concentrations of AOS, resulting in oxidative damage at the cellular level. Therefore, antioxid...
متن کاملA comparative study of some biochemical characteristics of peroxidase isoenzymes in rosemary plant (Rosmarinus officinalis L.)
Background & Aim: Rosemary (Rosmarinus officinalis L.) includes species that have high drug and nutritional values. Considering the importance of the antioxidant enzyme system as an effective factor in increasing the resistance of plants to different environmental stresses, in this research, some biochemical properties of catalase and peroxidase enzymes of rosemary pla...
