Metal-independent decomposition of hydroperoxides by halogenated quinones: detection and identification of a quinone ketoxy radical.
Proc. Natl. Acad. Sci. U. S. A. 106(28) , 11466-71, (2009) We have shown recently that halogenated quinones could enhance the decomposition of hydroperoxides and formation of alkoxyl/hydroxyl radicals through a metal-independent mechanism. However, neither the proposed quinone enoxy radical intermediate, nor the majo... |

Removal of halo-benzoquinone (emerging disinfection by-product) precursor material from three surface waters using coagulation.
Water Res. 47(5) , 1773-82, (2013) Halo-benzoquinones (HBQs) have been previously detected as disinfection by-products in chlorinated drinking water. The current work investigates the link between natural organic matter (NOM) characteristics and HBQ formation during bench-scale coagulation of ... |

Microbial anaerobic demethylation and dechlorination of chlorinated hydroquinone metabolites synthesized by basidiomycete fungi.
Appl. Environ. Microbiol. 70(1) , 385-92, (2004) The synthesis and degradation of anthropogenic and natural organohalides are the basis of a global halogen cycle. Chlorinated hydroquinone metabolites (CHMs) synthesized by basidiomycete fungi and present in wetland and forest soil are constituents of that cy... |

Interaction of exogenous quinones with membranes of higher plant chloroplasts: modulation of quinone capacities as photochemical and non-photochemical quenchers of energy in Photosystem II during light-dark transitions.
Biochim. Biophys. Acta 1604(2) , 115-23, (2003) Light modulation of the ability of three artificial quinones, 2,5-dibromo-3-methyl-6-isopropyl-p-benzoquinone (DBMIB), 2,6-dichloro-p-benzoquinone (DCBQ), and tetramethyl-p-benzoquinone (duroquinone), to quench chlorophyll (Chl) fluorescence photochemically o... |

Substrate water exchange in photosystem II core complexes of the extremophilic red alga Cyanidioschyzon merolae.
Biochim. Biophys. Acta 1837(8) , 1257-62, (2014) The binding affinity of the two substrate-water molecules to the water-oxidizing Mn₄CaO₅ catalyst in photosystem II core complexes of the extremophilic red alga Cyanidioschyzon merolae was studied in the S₂ and S₃ states by the exchange of bound ¹⁶O-substrate... |

Photoconsumption of molecular oxygen on both donor and acceptor sides of photosystem II in Mn-depleted subchloroplast membrane fragments.
Biochim. Biophys. Acta 1797(4) , 516-23, (2010) Oxygen consumption in Mn-depleted photosystem II (PSII) preparations under continuous and pulsed illumination is investigated. It is shown that removal of manganese from the water-oxidizing complex (WOC) by high pH treatment leads to a 6-fold increase in the ... |

Site-directed mutagenesis of basic arginine residues 305 and 342 in the CP 43 protein of photosystem II affects oxygen-evolving activity in Synechocystis 6803.
Biochemistry 38(5) , 1582-8, (1999) The intrinsic chlorophyll protein CP 43, a component of photosystem II (PS II) in higher plants, green algae, and cyanobacteria, is encoded by the psbC gene. Oligonucleotide-directed mutagenesis was employed to introduce mutations into a segment of psbC that ... |

Fluorescence induction of Photosystem II membranes shows the steps till reduction and protonation of the quinone pool.
J. Plant Physiol. 160(12) , 1499-506, (2003) Chlorophyll fluorescence induction (Chl-F) was investigated in Photosystem II (PSII)-enriched membranes, which predominantly include active (QB reducing) PSII reaction centres (RCs) and lack Photosystem I (PSI). The Chl-F curve of these preparations show a po... |

Multiflash experiments reveal a new kinetic phase of photosystem II manganese cluster assembly in Synechocystis sp. PCC6803 in vivo.
Biochemistry 44(28) , 9766-74, (2005) The assembly of Mn(2+) ions into the H(2)O oxidation complex (WOC) of the photosystem II (PSII) reaction center is a light-driven process, termed photoactivation. According to the "two-quantum" model, photoactivation involves two light-driven charge separatio... |

Involvement of acceptor side components of PSII in the regulatory mechanism of Plectonema boryanum grown photoautotrophically under diazotrophic condition.
Biochem. Biophys. Res. Commun. 194(3) , 1001-7, (1993) Alternating peaks of photosynthetic activity (P-phase) and nitrogen fixing activity (N-phase) were shown in Plectonema boryanum grown under diazotrophic condition in continuous light. In N-phase photosystem I activity increased by 35-45% and oxygen evolution ... |
