Plasma concentrations of free fatty acids are increased in metabolic syn-drome, and the increased fatty acids may cause cellular damage via the
induction of oxidative stress. The present study was designed to determine
whether the increase in fatty acids can modify the free sulfhydryl group in
position 34 of albumin (Cys34) and enhance the redox-cycling activity of
the copper–albumin complex in high-fat diet-induced obese mice.
Hydrogen economy represents the future of human civilization. Limited resources of our planet are compelling us to turn to renewable clean energy resources and hydrogen figures prominently as the energy carrier of a future sustainable energy system. There are significant challenges to be overcome in order to make hydrogen viable, in production, storage and power generation, while safety of operation is an ever-present factor that determines success or failure of a proposed solution.
Glutaredoxins (Grxs) have been shown to be critical in maintaining redox
homeostasis in living cells. Recently, an emerging subgroup of Grxs with
one cysteine residue in the putative active motif (monothiol Grxs) has been
The modification of chromium oxide added into iron oxide by co-precipitation method significantly prevents the sinterring of iron and iron oxide during repeated redox cycles. The activity of 4 redox cycles is stable and the H2/Fe ratio is almost the same with theoretical value.
Erythrocytic stages of the malaria parasitePlasmodium fal-ciparumrely on glycolysis for their energy supply and it is
unclear whether they obtain energy via mitochondrial res-piration albeit enzymes of the tricarboxylic acid (TCA) cycle
appear to be expressed in these parasite stages. Isocitrate
dehydrogenase (ICDH) is either an integral part of the
mitochondrial TCA cycle or is involved in providing
NADPH for reductive reactions in the cell.
Light/dark modulation of the higher plant Calvin-cycle
enzymes phosphoribulokinase (PRK) and NADP-depend-ent glyceraldehyde 3-phosphate dehydrogenase (NADP-GAPDH-A2B2) involves changes of their aggregation state
inaddition to redox changes of regulatory cysteines.Herewe
demonstrate that plants possess two different complexes
containing the inactive forms (a) of NADP-GAPDH and
PRK and (b) of only NADP-GAPDH, respectively, in
