6. Assembly and Function of Nitric Oxide Reductase from Paracoccus denitrificans
Sammanfattning : Bacterial denitrification is a part of the global nitrogen cycle and comprises the stepwise reduction of nitrate to molecular nitrogen, which is released to the atmosphere. Cytochrome c-dependent nitric oxide reductase (cNOR) from Paracoccus (P.) denitrificans catalyzes the reduction of nitric oxide to nitrous oxide and water. LÄS MER
7. Electron and Proton Transfer in Nitric Oxide Reductase : NO Binding, NO Reduction and no Pumping
Sammanfattning : Nitric oxide reductase (NOR) from Paracoccus denitrificans catalyzes the two electronreduction of NO to N2O (2NO + 2H+ + 2e- → N2O + H2O) as part of the process ofdenitrification, the step-wise reduction of nitrate to dinitogen. The NOR-catalyzedreaction is central in the nitrogen cycle, since in this step the N=N double bond isformed. LÄS MER
8. Kinetics of proton and electron transfer in heme-copper oxidases
Sammanfattning : Heme-copper oxidases are transmembrane proteins that are found in aerobic and anaerobic respiratory chains. During aerobic respiration, these enzymes reduce dioxygen to water. The energy released in the reaction is used to transport protons across a biological membrane. LÄS MER
9. Mechanistic Studies on Proton-Coupled Electron Transfer from Tyrosine and Tryptophan Derivatives
Sammanfattning : Proton-coupled electron transfer (PCET) from tyrosine (Y) and tryptophan (W) is vital to many redox reactions in Nature where PCET between several Ys, or Ws, or between a mix of Ys and Ws can be used to transfer electrons, or protons, or both over large distances of several Å. Studying the PCET reaction mechanisms of Y and W is important for fundamental knowledge, and can help researchers that wish to mimic redox reactions in Nature. LÄS MER
10. Proton transfer in nitric oxide reducing heme-copper oxidases
Sammanfattning : Heme-copper oxidases (HCuOs) are best known as terminal oxidases in the aerobic respiratory chain, in which they catalyze the reduction of oxygen to water. By receiving protons and electrons from opposite sides of the membrane as well as pumping protons, HCuOs contribute to the electrochemical proton gradient over the membrane that can be used for ATP synthesis.
