Examining Molecular Interactions of Proteins by Isotopic Labeling, Sample Formulation and Solid-State NMR Spectroscopy
… two large membrane proteins, E. coli cytochrome bo3 oxidase and A. thaliana cytochrome P450 monooxygenase 98A3. To obtain site-specific resolution in uniformly- 13C, 15N labeled samples of these proteins, hardware advances, new experimental techniques and increased dimensionality were combined. …

Structure and Function Relationships in Cytochrome Bo(3) Oxidase and Cytochrome Bd-I Oxidase From Escherichia Coli
… and function relationships in the two terminal oxidases in Escherichia coli have been investigated. Cytochrome bo3 oxidase, a member of the heme/copper superfamily, is found to have a semiquinone intermediate during turnover of quinol. Additionally, after the quinol is consumed and turnover …

Characterizations on bacterial photosynthesis and respiration with optical spectroscopy and magnetic resonance
… section, the semiquinone pocket in the bo3 oxidase from Escherichia coli is examined with pulsed EPR (Chapter 5). To get a clear picture of the hydrogen bonded protons, I have fully deuterated the enzyme and successfully generated the semiquinone signal, with which the Davies ENDOR are …

Biochemical characterization of a-type heme-copper oxidases in escherichia coli, bacillus subtilis and thermus thermophilus
Heme-copper oxidases (HCOs) couple the free energy of oxygen reduction and translocate protons across membrane to generate a proton electrochemical gradient, which was used to produce ATP by ATP synthase. Based on the sequences and structures of core subunits, they are classified into 3 types. …

Solid-state NMR studies of membrane proteins and membrane protein complexes
… are used to study a 144 kDa cytochrome bo3 ubiquinol oxidase demonstrating the power of this technique to investigate large membrane complexes in native environments.
