1. Heme A synthase from Bacillus subtilis and Aeropyrum pernix
Abstract : Respiration in animals, plants and many bacteria is dependent on heme A, which functions as a prosthetic group in a-type cytochromes (terminal energy-transducing oxidases in the electron transport chain that reduce molecular oxygen to water). Heme A synthase catalyses a chemically very demanding reaction, the conversion of one specific methyl side-group of heme O to a formyl group of heme A. READ MORE

2. The Physiological Cost of Antibiotic Resistance
Abstract : Becoming antibiotic resistant is often associated with fitness costs for the resistant bacteria. This is seen as a loss of competitiveness against the antibiotic-sensitive wild-type in an antibiotic-free environment. READ MORE

3. Synthesis of hemes found in heme-copper oxidases of Bacillus subtilis
Abstract : 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.

4. Alpha-1-microglobulin: Innate defence against pathological oxidation
Abstract : Oxidative stress has been implicated as an important factor in the progression of many diseases. An imbalance in the redox-system may cause oxidation of cells and molecules, which might subsequently lead to tissue damage. READ MORE

5. Genetics of Tetrapyrrole Synthesis in Gram-Positive Bacteria
Abstract : The organization and regulation of genes for tetrapyrrole synthesis were studied in low G+C Gram-positive bacteria. Clusters of genes encoding enzymes for tetrapyrrole biosynthesis were cloned from Bacillus sphaericus, Bacillus stearothermophilus, Brevibacillus brevis and Paenibacillus macerans. READ MORE
