1. 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
2. Studies on Haemproteins of Gram-positive Bacteria - Implications as Antibacterial Drug Targets
Sammanfattning : With the discovery of antibiotics, several diseases that were previously lethal is today readily cured, or so we thought. Some degree of resistance to one or several antibiotics can be found among many strains of clinical important bacteria. LÄS MER
3. 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
4. Heme Protein Biogenesis - Catalase in Enterococcus faecalis
Sammanfattning : Heme proteins form a large and diverse group of proteins which are involved in a variety of biological functions. The heme prosthetic group enables them to carry out redox reactions, transport electrons, bind gaseous molecules, and function as sensors. Despite their importance only little is generally known about heme protein biogenesis. LÄS MER
5. Quinone reduction sites and the role of heme in succinate:quinone reductase. Studies in Bacillus subtilis and Paracoccus denitrificans
Sammanfattning : Succinate:quinone reductase (SQR) is an enzyme in the respiratory system of aerobic cells. SQR catalyzes two reactions, the oxidation of succinate to fumarate and the reduction of quinone to quinol. These reactions are coupled by electron transfer within the enzyme from the site of succinate oxidation to the site of quinone reduction. LÄS MER
