Lignin peroxidase shares several structural features with the well-studied horseradish peroxidase and cytochrome c peroxidase but carries a higher redox potential. Here the heme domain of lignin peroxidase and the lignin peroxidase cyanide adduct was examined by 1HNMR spectroscopy, including nuclear Overhauser effect and two-dimensional measurements, and the findings were compared with those fo...

introduction : pemphigus comprises a group of diseases characterized by cutaneous and mucosal blistering. pemphigus vulgaris (pv) is the most common and important variant. recent reports have revealed the relatively high incidence of pv in iran. the onset or aggravation of many human diseases is attributed to oxidative stress and it has been suggested as one of the several factors responsible f...

results theophylline-treated rats showed mda level elevation and gpx activity reduction. quercetin treatment improved heart conditions and resulted in a significant reduction in mda levels and elevation in gpx activity. moreover, co-administration of quercetin and theophylline increased the heart weight significantly. furthermore, histophatological study showed no changes in the treated groups....

Herein, Cu–HMT and Ni–HMT were synthesized via a green synthetic method. possesses formidable peroxidase-mimic activity compared to Ni–HMT. However, the peroxidase-like of was strongly inhibited in presence DA.

plant materials have been found useful in decontamination of water polluted with phenolic compounds. the detoxification effect is due to peroxidases contained in plant tissue. enzyme mediated oxidative coupling of phenol is followed by precipitation of the formed polymer and its removal from the aqueous phase. a synthetic wastewater buffered at ph = 7.4 containing 0.9 mm phenol was treated in t...

Monoclonal antibodies against prostaglandin H (PGH) synthase have been used to precipitate cyclooxygenase and peroxidase activities from detergent-solubilized preparations of ram seminal vesicle microsomes. Approximately 85% of the solubilized cyclooxygenase activity was precipitated using an excess of anti-PGH synthase antibody; under similar conditions, immunoprecipitation of 60% of the diphe...
