1. Mutations in ribosomal protein L7/L12 : structural and functional studies
Sammanfattning : .... LÄS MER
2. tRNA Gene Structures in Bacteria
Sammanfattning : In bacteria, tRNA molecules are produced as precursors with additional nucleotides both upstream and downstream of the tRNA coding sequence. To generate a mature tRNA, the endoribonuclease RNase P removes the upstream sequence, while a number of enzymes can remove the downstream sequence. LÄS MER
3. Distal to Proximal—Functional Coupling in RNase P RNA-mediated Catalysis
Sammanfattning : RNase P is a ubiquitous ribonuclease responsible for removing the 5’ leader of tRNA precursor. Bacterial RNase P contains one RNA (RPR) and one protein (RPP) subunit. However, the number of protein variants depends on the origin. The RNA subunit is the catalytic subunit that in vitro cleaves its substrate with and without the protein subunit. LÄS MER
4. Dynamic Organization of Molecular Machines in Bacteria
Sammanfattning : Bacterial cells were once treated as membrane-enclosed bags of cytoplasm: a homogeneous, undifferentiated suspension in which polymers (proteins, nucleic acids, etc.) and small molecules diffused freely to interact with each other. LÄS MER
5. Morphological changes in mycobacteria
Sammanfattning : Morphological variations at different stages and conditions of growth has been observed frequently in various mycobacteria. Despite years of research, the molecular basis of such variations is still not clear and requires further elucidation. LÄS MER
