  1. 1. Multiple regulatory inputs for hierarchical control of phenol catabolism by Pseudomonas putida

    Författare :W. K. Anjana Madhushani; Victoria Shingler; Livia Leoni; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; P. putida; Phenol catabolism; dmpR; dmp-System; 5’-LR; Carbon Catabolite Repression; Transcriptional Translational regulation; Crc; CrcZ; CrcY; Hfq;

    Sammanfattning : Metabolically versatile bacteria have evolved diverse strategies to adapt to different environmental niches and respond to fluctuating physico-chemical parameters. In order to survive in soil and water habitats, they employ specific and global regulatory circuits to integrate external and internal signals to counteract stress and optimise their energy status.

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Global regulatory factors that impact metabolic and lifestyle choices in Pseudomonas putida

    Författare :Lisa Wirebrand; Victoria Shingler; Matthew Francis; Carlos Balsalobre; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Pseudomonas putida; c-di-GMP; motility; ppGpp; DksA; biofilm dispersal; transcriptional and translational regulation; dmp-system; phenol catabolism; carbon repression control; plasmid stability;

    Sammanfattning : Pseudomonas putida strains have a broad metabolic capacity and are innately resistant to many harmful substances – properties that make them of interest for a number of industrial and biotechnological application. They can rapidly adapt to changes in physico-chemical parameters in the soil and water environments they naturally inhabit. LÄS MER

  5. 4. 4-chlorophenol biodegradation by Arthrobacter chlorophenolicus A6

    Författare :Karolina Nordin; Janet Jansson; Lawrence P. Wackett; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

    Sammanfattning : A microorganism was isolated which could grow on unusually high concentrations of the toxic pollutant 4-chlorophenol. Taxonomic studies showed that the microorganism constituted a novel species within the genus Arthrobacter and it was named Arthrobacter chlorophenolicus A6. A. LÄS MER

  7. 5. On the role of ppGpp and DksA mediated control of σ54-dependent transcription

    Författare :Lisandro Bernardo; Victoria Shingler; Victor de Lorenzo; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ppGpp; DksA; σ54-transcription; global regulation; E. coli; P. putida; Molecular biology; Molekylärbiologi;

    Sammanfattning : The σ54-dependent Po promoter drives transcription of an operon that encodes a suite of enzymes for (methyl)phenols catabolism. Transcription from Po is controlled by the sensor-activator DmpR that binds (methyl)phenol effectors to take up its active form. LÄS MER
