6. Structure and Function of Cytochrome c Oxidase
Sammanfattning : Aerobic organisms, ranging from bacteria to humans, obtain their energy through the process of respiration. Electrons from the breakdown of food are transported through the membrane-bound enzyme complexes of the respiratory chain, to the terminal acceptor molecule, oxygen. LÄS MER
7. Structure Analysis of a Transient Protein Complex - NMR, X-ray crystallographic and Mass Spectrometric Studies of the Soluble Domains of the Proton-Pump Transhydrogenase from E. coli
Sammanfattning : Interactions between macromolecules in the cell are fundamental to life. However, many interactions are of a transient nature and are as such difficult to study at the atomic level using existing techniques. LÄS MER
8. Generation and exploitation of proton motive force: Biochemical and structural analysis of three bacterial integral membrane proteins
Sammanfattning : Proton motive force, a necessity for all living cells, is generated and exploited by asignificant number of membrane-bound enzymes and transporters. The focus of thisthesis was to understand the physiological relevance, structure and mechanism of threesuch bacterial enzymes: proteorhodopsin; transhydrogenase; and AcrB. LÄS MER
9. Acceptor-Doped BaZrO3 Perovskite: Synthesis, Structure and Proton Conductivity
Sammanfattning : Acceptor-doped perovskite oxides exhibit significant proton conductivity in hydrogen containing atmospheres. Therefore, they have potential for use as separator materials for various electrochemical devices including gas sensors, electrolysers and fuel cells. LÄS MER
10. Regulation of proton-coupled electron transfer in cytochrome c oxidase : The role of membrane potential, proton pathways and ATP
Sammanfattning : Cytochrome c oxidase (CytcO) is the final electron acceptor of the respiratory chain. In this chain a current of electrons, derived from degradation of nutrients, along with protons, are used to reduce oxygen to water. The reaction is exergonic and the excess energy is used to pump protons across the membrane. LÄS MER
