https://www.selleckchem.com/products/(-)-Epigallocatechin-gallate.html The review is focused on analysis of the mechanisms of temperature-dependent regulation of electron transport and ATP synthesis in chloroplasts of higher plants. Importance of photosynthesis thermoregulation is determined by the fact that plants are ectothermic organisms, whose own temperature depends on the ambient temperature. The review discusses the effects of temperature on the following processes in thylakoid membranes (i) photosystem 2 activity and plastoquinone reduction; (ii) electron transfer from plastoquinol (via the cytochrome b6f complex and plastocyanin) to photosystem 1; (iii) transmembrane proton transfer; and (iv) ATP synthesis. The data on the relationship between the functional properties of chloroplasts (photosynthetic transfer of electrons and protons, functioning of ATP synthase) and structural characteristics of membrane lipids (fluidity) obtained by electron paramagnetic resonance studies are presented.2-Cys peroxiredoxins are abundant thiol proteins that react efficiently with a wide range of peroxides. Unlike other enzymes, their exceptionally high reactivity does not rely on cofactors. The mechanism of oxidation and reduction of peroxiredoxins places them in a good position to act as antioxidants as well as key players in redox signaling. Understanding of the intimate details of peroxiredoxin functioning is important for translational research.Several ferryl states of the catalytic heme a3-CuB center of the respiratory cytochrome c oxidases (CcOs) are observed during the reduction of O2 to H2O. One of the P-type ferryl forms, PM, is produced by the reaction of the two-electron reduced CcO with O2. In this state, the heme a3 iron is in the ferryl state and a free radical should be also present at the catalytic center. However, the energetics of the PM formation has not been experimentally established yet. Here, the generation of PM by the reaction of oxidized bovine CcO
