1. Heme-copper oxidases and nitric oxide : Reaction mechanisms and supercomplex formation
Abstract : In the denitrification process where nitrate is stepwise reduced to nitrogen gas, the toxic molecule nitric oxide (NO) is formed as an intermediate. Nitric oxide is produced by the enzyme cd1 Nitrite reductase (cd1NiR) by reduction of nitrite and is later reduced to nitrous oxide by nitric oxide reductase (cNOR). READ MORE

2. Kinetic assays for RNA-cleaving deoxyribozymes and other nucleases
Abstract : In this thesis two different assays for real-time RNA-cleaving deoxyribozyme and general nuclease kinetics are presented. Previous publications on nuclease kinetic assays have been riddled with drawbacks of labeling, discontinuity, cost etc. READ MORE

3. Active Transport of Ions across Biomembranes : A Kinetic Study of Cytochrome c Oxidase Reconstituted into Phospholipid Vesicles
Abstract : Ion transport across membranes is of uttermost importance for us. It is the foundation for signaling of various kinds e.g. in the nerve-system. READ MORE

4. Nitric Oxide Reductase from Paracoccus denitrificans : A Proton Transfer Pathway from the “Wrong” Side
Abstract : Denitrification is an anaerobic process performed by several soil bacteria as an alternative to aerobic respiration. A key-step in denitrification (the N-N-bond is made) is catalyzed by nitric oxide reductase (NOR); 2NO + 2e- + 2H+ → N2O + H2O. READ MORE

5. Proton pathways in energy conversion : K-pathway analogs in O2- and NO-reductases
Abstract : Oxygen and nitric oxide reductases are enzymes found in aerobic and anaerobic respiration, respectively. Both enzyme groups belong to the superfamily of Heme-Copper Oxidases, which is further divided into several subgroups: oxygen-reducing enzymes into A-, B- and C-type and nitric oxide reductases into qNORs and cNORs.
