16. 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
17. Transmembrane proton transfer in biological systems : an investigation of bacterial and archaeal haem-copper oxidases
Sammanfattning : Haem-copper oxidases are membrane-bound protein complexes that catalyse the reduction of dioxygen to water in the respiratory chain. These enzyme complexes are molecular machines that couple the free energy released from this reaction to pump protons across the membrane. LÄS MER
18. Proton transfer in cytochrome c oxidase : how, when and why
Sammanfattning : .... LÄS MER
19. Monitoring Proton Exchange and Triplet States with Fluorescence
Sammanfattning : Fluorescent molecules commonly shift to transient dark states, induced bylight or triggered by chemical reactions. The transient dark states can beused as probes of the local environment surrounding the fluorescent molecules,and are therefore attractive for use in biomolecular applications. LÄS MER
20. Experimental studies of proton translocation reactions in biological systems : Electrogenic events in heme-copper oxidases
Sammanfattning : Terminal heme-copper oxidases (HCuOs) are transmembrane proteins that catalyze the final step in the respiratory chain - the reduction of O2 to H2O, coupled to energy conservation by generation of an electrochemical proton gradient. The most extensively investigated of the HCuOs are the aa3-type oxidases, to which cytochrome c oxidase (CytcO) belongs, which uses energy released in the O2-reduction for proton pumping. LÄS MER
