  2. 1. Versatile and Antique World of RNA : The Simplicity of RNA Mediated Catalysis

    Author : Ema Kikovska; Leif Kirsebom; Venkat Gopalan; Uppsala universitet; []
    Keywords : Microbiology; RNA Catalysis; RNase P; Metal ions; tRNA Processing; Ribozyme; Mikrobiologi;

    Abstract : RNA is the only biological molecule that can function both as a repository of information and as a catalyst. This, together with the ability to self-replicate, led to recognition of RNA as ‘prelude to life’.My work highlights some of the important features of RNA as a catalyst, exemplified by RNase P.

  4. 2. CopA and CopT: The Perfect RNA Couple

    Author : Jacoba G. Slagter-Jäger; Gerhart Wagner; Wolfgang Nellen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; antisense RNA; plasmid; U-turn; four-way junction; RNA-RNA interaction; Hfq; Mikrobiologi; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

    Abstract : Antisense RNAs regulate gene expression in many bacterial systems. The best characterized examples are from prokaryotic accessory elements such as phages, plasmids and transposons. Many of these antisense RNAs have been identified as plasmid copy number regulators where they regulate the replication frequency of the plasmid by negative feedback. READ MORE

  6. 4. Macromolecular Matchmaking : Mechanisms and Biology of Bacterial Small RNAs

    Author : Erik Holmqvist; E. Gerhart H. Wagner; Udo Bläsi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Small RNA; sRNA; non-coding RNA; antisense; gene regulation; post-transcriptional regulation; translational control; outer membrane protein; OmpA; MicA; biofilm; flagella; curli; bistability; Lrp; MicF; CsgD; FlgM; OmrA; OmrB; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : Cells sense the properties of the surrounding environment and convert this information into changes in gene expression. Bacteria are, in contrast to many multi-cellular eukaryotes, remarkable in their ability to cope with rapid environmental changes and to endure harsh and extreme milieus. READ MORE

  7. 5. Multi-omics investigation into bacterial evolution

    Author : Karl Dyrhage; Siv Andersson; Dan I. Andersson; Jay Hinton; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; bacterial evolution; cellular complexity; comparative genomics; transcriptomics; proteomics; fructophilic lactic acid bacteria; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : The focus of this thesis is the investigation of the evolution and cellular processes of Tuwongella immobilis and Apilactobacillus kunkeei, two bacterial species with different levels of genomic and cellular complexity, using a multi-omics approach.In the first study we examined the proteome of T.
