1. Activation, reaction mechanism and allosteric regulation of the anaerobic ribonucleotide reductase from bacteriophage T4
Abstract : Ribonucleotide reductase (RNR) catalyse the conversion of ribonucleotides to their corresponding deoxyribonucleotides in all organisms. The deoxyribonucleotides are the building blocks for DNA. Three different classes of RNR are found, class I, II and III. READ MORE

2. Translational accuracy, ribozyme efficiency and NAD metabolism in Escherichia coli
Abstract : Interactions between the translational machinery and mRNA in Escherichia coli have been studied. In the first section nonsense codon readthrough and changed translational reading frame were measured in different growth phases. READ MORE

3. Structural studies on aerobic and anaerobic respiratory complexes
Abstract : All respiratory pathways, whether aerobic or anaerobic, are based on formation of an electrochemical proton gradient called proton motive force (pmf) that drives ATP formation. Membrane-bound respiratory complexes translocate protons across the membrane from a region of low [H+] and negative electrical potential to a region of high [H+] and positive electrical potential.
