BACKGROUND The observed relationships between visfatin, peroxidases activity, and metabolic syndrome (MetS) are inconsistent; therefore, this study was undertaken to understand these relationships. METHODS This cross-sectional study was conducted as a part of the Isfahan Healthy Heart Program, Iran. A blood sample of 90 MetS and non-MetS patients were used to estimate total cholesterol (TC), ...

abstract peroxidases are a group of oxidoreductases that are produced by a number of microorganisms and plants, and catalyse the reduction of peroxides. peroxidases are widely used in clinical biochemistry and enzyme immunoassay. horseradish peroxidase isoenzyme c (hrp) is one of the characterized peroxidases. the structure of the enzyme is largely alpha helical. kinetics studies of peroxidase ...

Indole-3-acetic acid (IAA) can be oxidized via two mechanisms: a conventional hydrogen-peroxide-dependent pathway, and one that is hydrogen-peroxide-independent and requires oxygen. It has been shown here for the first time that only plant peroxidases are able to catalyse the reaction of IAA oxidation with molecular oxygen. Cytochrome c peroxidase (CcP), fungal peroxidases (manganese-dependent ...

White rot fungi have one of the most efficient oxidative lignin degradation systems, and present an enzymatic complex that is responsible for digesting lignocellulosic matter. The aim this study was to evaluate production laccase total peroxidases by Ganoderma lucidum via solid-state fermentation using açaí seeds marupá (Simarouba amara) sawdust unsupplemented supplemented with wheat, corn rice...

The wastewater that originates from the widespread usage of synthetic dyes in industry have become a severe environmental problem. Several efforts been made to develop new types treatment which are capable performing degradation environment. Within this scope, much attention has drawn enzymatic approaches, mainly ones applying oxidative enzymes, such as peroxidases. A recently discovered superf...

Lignins are aromatic heteropolymers that arise from oxidative coupling of lignin precursors, including lignin monomers (p-coumaryl, coniferyl, and sinapyl alcohols), oligomers, and polymers. Whereas plant peroxidases have been shown to catalyze oxidative coupling of monolignols, the oxidation activity of well-studied plant peroxidases, such as horseradish peroxidase C (HRP-C) and AtPrx53, are q...

Fungal secretory peroxidases mediate fundamental ecological functions in the conversion and degradation of plant biomass. Many of these enzymes have strong oxidizing activities towards aromatic compounds and are involved in the degradation of plant cell wall (lignin) and humus. They comprise three major groups: class II peroxidases (including lignin peroxidase, manganese peroxidase, versatile p...

Panaeolus sphinctrinus, Panaeolus papilionaceus, and Coprinus friesii are described as producers of ligninolytic enzymes. P. papilionaceus and P. sphinctrinus both produced a laccase. In addition, P. sphinctrinus produced a manganese peroxidase. C. friesii secreted a laccase and two peroxidases similar to the peroxidase of Coprinus cinereus. The purified laccases and peroxidases were characteri...

Ligninolytic heme peroxidases comprise an extensive family of enzymes, which production is characteristic for white-rot Basidiomycota. The majority of fungal heme peroxidases are encoded by multigene families that differentially express closely related proteins. Currently, there were very few attempts to characterize the complete multigene family of heme peroxidases in a single fungus. Here we ...
