introduction: the fate of xenobiotics that is present, increasing day by day. the increasing fates altered or inhibit the metabolic activities like detoxification and biotransformation. methods: the present study highlights this slow biotransformation and detoxification on the basis of specific enzymes which have a say in assessment of mercuric chloride toxicity and modulation by panax ginseng ...
background oxidative stress plays a major pathogenic role in liver injury following chronic hepatitis b. glutathione peroxidase (gpx) has a central role in regulating the oxidative state. hepatitis b virus (hbv) results in down-regulation of gpx. on the other hand, iron homeostasis is disrupted in hbv infected patients. therefore, the objective of this study was to assess the interplay of gpx a...
Protection of nitrogenase against oxygen inactivation in diazotrophs involves numerous strategies. Glutathione is known to play an important role in scavenging oxyradicals in many living systems. The involvement of glutathione (reduced) (GSH), glutathione peroxidase (GPX) and glutathione reductase (GR) in the protection of nitrogenase in free living diazotrophs is reported here for the first ti...
In contrast to neutrophils or B-lymphocytes, cells of the monocytic lineage like rat macrophages, human peripheral blood monocytes and Mono Mac 6 cells contain a strong inhibitor of 5-lipoxygenase (5-LO) activity, which scavenges hydroperoxides and inhibits 5-LO activity in broken-cell preparations in the absence of exogenously added thiols. Chromatographic purification of the inhibitor from th...
Synechocystis PCC 6803 contains two types of glutathione peroxidase-like proteins (GPX-1 and GPX-2) that utilize NADPH but not reduced glutathione and unsaturated fatty acid hydroperoxides or alkyl hydroperoxides. The steady-state transcript level of gpx-1 gradually increased under oxidative stress conditions imposed by high light intensity, high salinity, or application of methylviologen or t-...
In the current issue of Circulation, Jin et al1 provide insight into how a deficiency in the activity of the primary plasma peroxide-metabolizing enzyme glutathione peroxidase-3 (GPx-3) creates a prothrombotic state with vascular dysfunction. Mice deficient in GPx-3 are shown to have elevated soluble P-selectin (a marker of platelet and prothrombotic activity) and enhanced responses to experime...

Crystal and solution structural studies of mouse phospholipid hydroperoxide glutathione peroxidase 4
The mammalian glutathione peroxidase (GPx) family is a key component of the cellular antioxidative defence system. Within this family, GPx4 has unique features as it accepts a large class of hydroperoxy lipid substrates and has a plethora of biological functions, including sperm maturation, regulation of apoptosis and cerebral embryogenesis. In this paper, the structure of the cytoplasmic isofo...
