The presence of peroxidase in the uterus of the estrogeninjected ovariectomized rat and in the Walker carcinosarcoma No. 256 of rats has been reported previously (1, 2). In view of the fact that both these tissues undergo rapid proliferation, it was thought of interest to survey several other rat tissues to determine whether peroxidase might be generally associated with proliferation. Bancroft ...

The peroxidase/reverse micelle (RM) system effectively catalyzed the oxidation reaction in cyclohexane, while peroxidase from bitter gourd in aqueous buffer exhibited low catalytic activity. The oxidation of methyl parathion (MPT) has been optimized with effects of pH in the water pools, concentration of peroxidase and degree of surfactant hydration (Wo). The peroxidase/RM system showed a stron...

Ligninolytic extracellular enzymes, including lignin peroxidase, are topical owing to their high redox potential and prospective industrial applications. The prospective applications of lignin peroxidase span through sectors such as biorefinery, textile, energy, bioremediation, cosmetology, and dermatology industries. The litany of potentials attributed to lignin peroxidase is occasioned by its...

abstract kinetic properties of root of peroxidase of gundelia tournefortii investigated at different ph, temperature and different inhibitors. maximum activity of peroxidase achieved at ph 5.5-6 in according to type of substrate. activity of peroxidase increased at constant concentration of h2o2 and different concentration of guaiacol, catechol and pyrogallol. the maximum activity in presence o...

Sheep airway mucus can potently scavenge hydrogen peroxide, an important mediator of airway inflammation. Here, the scavenging activity was identified as a peroxidase produced by goblet cells of the airway epithelium and secreted into the airway lumen. Ovine airway peroxidase activity was purified approximately 100-fold from airway lavage fluid in two steps, using cation exchange and lectin aff...

Plant peroxidases are one of the most extensively studied group of enzymes which find applications in the environment, health, pharmaceutical, chemical and biotechnological processes. Class III secretary peroxidase from alfalfa (Medicago sativa) has been characterized using bioinformatics approach Physiochemical properties and topology of alfalfa peroxidase were compared with that of soybean an...

Glutathione peroxidases are widespread among eukaryotic organisms and function as a major defense against hydrogen peroxide and organic peroxides. However, glutathione peroxidases are not well studied among prokaryotic organisms and have not previously been shown to promote bacterial virulence. Recently, a gene with homology to glutathione peroxidase was shown to contribute to the antioxidant d...

We present evidence of two peroxidases in maize (Zea mays L.) mitochondria. One of these uses guaiacol and the other uses cytochrome c as the electron donor. Treatments of fresh mitochondria with protease(s) indicate that ascorbate and glutathione peroxidases are likely bound to the mitochondria as cytosolic contaminants, whereas guaiacol and cytochrome peroxidases are localized within the mito...
