    Substrate Water Oxygen Exchange in Photosystem II: Insights from Mutants and Ca vs. Sr Substitution

    Oxygen-18 exchange kinetics have been conducted for three point mutants associated with the oxygen evolving core of PSII and for centers that have undergone biosynthetic Sr/Ca exchange. The mutants D1-D170H, D...

    Near Infrared Yb3+ Vibronic Sideband Spectroscopy of Proteins: Amino-Acid Side Chain Models

    Recently, we have reported the use of near-infrared (NIR) Yb3+ vibronic sideband (VSB) spectroscopy to obtain structural information of metal-binding sites in proteins (1). In the NIR fluorescence spectrum of met...

    The quenching characteristics of potassium iridic chloride and their meaning for the origin of chlorophyll fluorescence components

    To understand the origins of the different lifetime components of photosystem 2 (PS2) chlorophyll (Chl) fluorescence we have studied their susceptibility to potassium iridic chloride (K2IrCl6) which has been show...

    Mutagenesis by random cloning of an Escherichia coli kanamycin resistance gene into the genome of the cyanobacterium Synechocystis PCC 6803: Selection of mutants defective in photosynthesis

    Photosynthetic mutants of the cyanobacterium Synechocystis PCC 6803 were produced by a random cartridge mutagenesis method leading to gene inactivation. This procedure relies on random ligation of an Escherichia ...
