1. 1. Proton pathways in energy conversion : K-pathway analogs in O2- and NO-reductases

   Författare :Nathalie Gonska; Pia Ädelroth; Alessandro Giuffré; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heme-copper oxidase; cytochrome c oxidase; membrane protein; respiration; electron transfer; proton transfer; redox reaction; metalloprotein; non-heme iron; cytochrome ba3; flow-flash; carbon monoxide; liposome; respiratory control ratio; Biochemistry; biokemi;

   Sammanfattning : Oxygen and nitric oxide reductases are enzymes found in aerobic and anaerobic respiration, respectively. Both enzyme groups belong to the superfamily of Heme-Copper Oxidases, which is further divided into several subgroups: oxygen-reducing enzymes into A-, B- and C-type and nitric oxide reductases into qNORs and cNORs.

3. 2. Structural studies of ba3-type cytochrome c oxidase using serial crystallography and X-ray absorption spectroscopy

   Författare :Doris Zoric; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ba3-type cytochrome c oxidase; structural biology; X-rays; serial X-ray crystallography; X-ray absorption spectroscopy; enzyme reaction dynamics;

   Sammanfattning : Cytochrome c oxidase (CcO) catalyses the reduction of molecular oxygen to water while the energy released in this process is used transport protons “up-hill” across an energy transducing biological membrane, creating a proton-motive force for ATP synthesis. Given its key role in energy transduction in organisms, proton pumping has been extensively studied across species. LÄS MER

4. 3. Microcrystallization in lipidic cubic phase and serial crystallography studies of cytochrome c oxidase

   Författare :Cecilia Safari; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Serial crystallography; Cytochrome c oxidase; Microcrystallization in lipidic cubic phase;

   Sammanfattning : Life in all living organisms depend on chemical processes performed by proteins, which are molecular machineries encoded in the DNA. Cytochrome c oxidase (CcO) is a membrane protein essential for cellular respiration, a process in which chemical energy enters the electron transport chain in the form of electrons and is transformed to ATP via a proton gradient.

5. 4. Lipidic Cubic Phase Microcrystallization and its Application in Serial Crystallography

   Författare :Rebecka Andersson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Structural biology; Lipidic Cubic Phase; Cytochrome c oxidase; Serial Crystallography;

   Sammanfattning : Every living organism contain a cell membrane which is an important cell structure with a vast variety of different functions such as cell signaling, transportation and energy production. One of the most important functions is to produce energy for the cell to thrive. LÄS MER

7. 5. Microcrystallization and structural studies of proteins by serial crystallography and x-ray scattering

   Författare :Owens Uwangue; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Proteins are the most complex and versatile biomolecules known, with essential roles in all cellular and physiological processes. They constitute the main structural components of cells, catalyze most biochemical reactions, regulate gene expression, modulate immune responses, and form tissues. LÄS MER
