  1. 16. Free energy calculations of G protein-coupled receptor modulation : New methods and applications

    Author : Willem Jespers; Hugo Gutiérrez-de-Terán; Johan Åqvist; Jonathan Essex; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; G protein-coupled receptor; adenosine receptor; molecular dynamics; free energy perturbation; homology modeling; computer simulations; conformational selectivity; binding free energy.; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Abstract : G protein-coupled receptors (GPCRs) are membrane proteins that transduce the signals of extracellular ligands, such as hormones, neurotransmitters and metabolites, through an intracellular response via G proteins. They are abundant in human physiology and approximately 34% of the marketed drugs target a GPCR. READ MORE

  2. 17. Computational Studies of Protein Synthesis on the Ribosome and Ligand Binding to Riboswitches

    Author : Christoffer Lind; Johan Åqvist; Alexander MacKerell Jr; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Binding free energy; Ribosome; Codon reading; Translation initiation; Translation termination; Mitochondrial translation; Release factor; Purine riboswitch; Molecular Dynamics; Free Energy Perturbation; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Abstract : The ribosome is a macromolecular machine that produces proteins in all kingdoms of life. The proteins, in turn, control the biochemical processes within the cell. It is thus of extreme importance that the machine that makes the proteins works with high precision. READ MORE

  3. 18. Bacterial DNA repair and molecular search

    Author : Arvid H. Gynnå; Johan Elf; Stephen Kowalczykowski; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA repair; DNA damage; homologous recombination; homologous repair; recombination; RecA; I-SceI; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Abstract : Surveillance and repair of DNA damage is necessary in all kinds of life. Different types of DNA damage require different repair mechanisms, but these mechanisms are often similar in all domains of life. The most serious type of damage, double stranded DNA breaks, are for example repaired in conceptually similar ways in both bacteria and eukaryotes. READ MORE

  4. 19. Rate and Accuracy of Bacterial Protein Synthesis

    Author : Magnus Johansson; Måns Ehrenberg; Jon Lorsch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein synthesis; ribosome; peptidyl transfer; rate-accuracy trade-off; kinetics; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Abstract : High levels of accuracy in transcription, aminoacylation of tRNA, and mRNA translation are essential for all life forms. However, high accuracy also necessarily means large energy dissipation and slow kinetics. Therefore, in vivo there is a fine tuned balance between rate and accuracy of key chemical reactions.

  5. 20. Mechanisms and Inhibition of EF-G-dependent Translocation and Recycling of the Bacterial Ribosome

    Author : Anneli Borg; Måns Ehrenberg; Ruben Gonzalez; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein synthesis; Elongation factor G; Translocation; Ribosome recycling; Fusidic acid; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Abstract : The GTPase elongation factor G (EF-G) is an important player in the complex process of protein synthesis by bacterial ribosomes. Although extensively studied much remains to be learned about this fascinating protein. READ MORE
