6. Structural Plasticity and Function in Cytochrome cd1 Nitrite Reductase
Sammanfattning : Cytochrome cd1 nitrite reductase is a bifunctional enzyme, which catalyses the one-electron reduction of nitrite to nitric oxide, and the four-electron reduction of oxygen to water. The latter is a cytochrome oxidase reaction. Both reactions occur on the d1 haem iron of the enzyme. LÄS MER
7. Structural elements involved in protein-mediated proton transfer : Implications from studies of cytochrome c oxidase
Sammanfattning : Proton transfer is one of the most common reactions in biological systems. During energy conversion inside a cell, proton transfer is crucial to maintain an electrochemical proton gradient across the cell membrane. This gradient is in turn used to e.g. LÄS MER
8. Bacterial Terminal Oxidases. Studies in Bacillus subtilis
Sammanfattning : The final step in aerobic respiratory pathways is catalyzed by terminal oxidases. Bacteria generally have two or more terminal oxidases. Aerobically grown Bacillus subtilis synthesize three terminal oxidases: one cytochrome c oxidase, cytochrome caa3 and two quinol oxidases, cytochrome aa3 and cytochrome bd. LÄS MER
9. 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
10. Synthesis of hemes found in heme-copper oxidases of Bacillus subtilis
Sammanfattning : The last step of aerobic respiration, the reduction of dioxygen to water, is catalysed by terminal oxidases. These oxidases can be divided into two unrelated families, the heme-copper oxidases and the cytochrome bd-type oxidases. These enzymes contain two or more heme molecules as prosthetic groups. LÄS MER
