  2. 1. In search of a biosensor for DNT detection : Studies of inducer response and specificity of DntR

    Author : Rosa Lönneborg; Peter Brzezinski; Ray Dixon; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DntR; transcriptional regulation; gfp; nitro-aromatic compounds; LysR family; LTTR; TNT; DNT; FACS; directed evolution; random mutagenesis; recombination; structure determination; biokemi; Biochemistry;

    Abstract : The primary aim of the work presented in this thesis was to change the inducer specificity of the DntR protein in order to improve the response to DNT. The long-term goal is to use this protein in a biosensor for DNT, a signature compound for detection of the explosive TNT. READ MORE

  4. 2. Deciphering control of Mechano-Transcription Activators of σ54-RNA polymerase

    Author : Henrik Seibt; Victoria Shingler; Uwe H. Sauer; Ray Dixon; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transcriptional regulation; P. putida; V. cholerae; AAA ; bEBP; B-linker; DmpR; Phenol catabolism; VCA0117; Type VI secretion; molekylärbiologi; Molecular Biology;

    Abstract : To survive and proliferate, bacteria have to respond to a plethora of fluctuating signals within their habitats. Transcriptional control is one crucial entry point for such signal-responsive adaption responses. READ MORE

  5. 3. PII proteins as global regulators of bacterial nitrogen metabolism

    Author : Pedro Filipe Teixeira; Stefan Nordlund; Ray Dixon; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rhodospirillum rubrum; nitrogen metabolism; signal transduction; PII proteins; Biochemistry; Biokemi; Biochemistry; biokemi;

    Abstract : Nitrogen is an essential element to sustain life, being a component of most biological macromolecules. In spite of the abundance of gaseous N2, the availability of nitrogen compounds that can be readily used by most microorganisms is scarce and its production energetically demanding. READ MORE
