  3. 2. Reaction-Diffusion kinetics of Protein DNA Interactions

    Författare :Anel Mahmutovic; Johan Elf; David van der Spoel; Pieter Rein ten Wolde; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; umbrella sampling; molecular dynamics; RDME; PDE; sliding; intersegment transfer; hopping; sterics; intersegment transfer; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : Transcription factors need to rapidly find one specific binding site among millions of nonspecific sites on the chromosomal DNA. In this thesis I use various aspects of reaction-diffusion theory to investigate the interaction between proteins and DNA and to explain the searching, finding and binding to specific operator sites.

    Sammanfattning : Studies of ribosomal reading frame maintenance are often based on frameshift mutation suppression experiments. In this thesis, suppression of a frameshift mutation in Salmonella enterica serovar Typhimurium by a tRNA and a ribosomal protein are described. LÄS MER

  5. 4. Statistical molecular design, QSAR modeling, and scaffold hopping – Development of type III secretion inhibitors in Gram negative bacteria

    Författare :Markus Dahlgren; Mikael Elofsson; Bo Nordén; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistical molecular design; QSAR; synthesis; type III secretion; virulence; scaffold hopping; Bioorganic chemistry; Bioorganisk kemi; datorlingvistik; computational linguistics;

    Sammanfattning : Type III secretion is a virulence system utilized by several clinically important Gram-negative pathogens. Computational methods have been used to develop two classes of type III secretion inhibitors, the salicylidene acylhydrazides and the acetylated salicylanilides. LÄS MER
