1. Characterization of the DNA-Binding Properties of the Cyanobacterial Transcription Factor NtcA
Sammanfattning : Nitrogen is an essential building block of proteins and nucleic acids and, therefore, crucial for the biosphere. Nearly 79 % of the air consists of nitrogen, but in the form of nitrogen gas (N2), which cannot be utilized by most organisms. LÄS MER
2. Cyanobacterial Hydrogen Metabolism - Uptake Hydrogenase and Hydrogen Production by Nitrogenase in Filamentous Cyanobacteria
Sammanfattning : Molecular hydrogen is a potential energy carrier for the future. Nitrogen-fixing cyanobacteria are a group of photosynthetic microorganisms with the inherent ability to produce molecular hydrogen via the enzyme complex nitrogenase. This hydrogen is not released, however, but is recaptured by the bacteria using an uptake hydrogenase. LÄS MER
3. Cyanobacterial Hydrogen Metabolism : Regulation and Maturation of Hydrogenases
Sammanfattning : In times with elevated CO2 levels and global warming there is a need of finding alternatives to carbon based energy carriers. One such environmental friendly solution could be H2 produced by living organisms. LÄS MER
4. Regulation, structure and function of glutathione reductase and its transcriptional regulator NtcA from the cyanobacterium Anabaena PCC 7120
Sammanfattning : Glutathione reductase (GR) is an important antioxidant enzyme in all aerobic life. Theenzyme was purified from cyanobacterium Anabaena PCC 7120 and overexpressed inEscherichia coli. It has physicochemical and kinetic properties similar to GR fromother sources, but unique features in the pyridine nucleotide-binding site. LÄS MER
5. Endovascular occlusion methods in non-traumatic cardiac arrest
Sammanfattning : Approximately 10% of out-of-hospital cardiac arrest patients survive to hospital discharge. An important factor for survival is perfusion to the coronary and cerebral circulations during cardiopulmonary resuscitation (CPR). LÄS MER
