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

   Author : W. K. Anjana Madhushani; Victoria Shingler; Livia Leoni; Umeå universitet; []
   Keywords : 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;

   Abstract : 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.

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

   Author : Lisa Wirebrand; Victoria Shingler; Matthew Francis; Carlos Balsalobre; Umeå universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

5. 3. Dynamic regulation of the Mig1 transcriptional repressor under glucose de/repression

   Author : Sviatlana Shashkova; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cell signalling; glucose repression; Mig1; phosphorylation; Saccharomyces cerevisiae;

   Abstract : The budding yeast Saccharomyces cerevisiae AMP-activated protein kinase/SNF1 is a member of a highly conserved protein family present in all eukaryotes. Snf1 regulates energy homeostasis; in yeast, it is best-known for its role in cellular adaptation to glucose limitation. READ MORE

6. 4. Function and regulation of the Yeast Mig1 repressor

   Author : Jonas Östling; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; glucose repression; Mig1; zinc finger protein; Saccharomyces cerevisiae; Kluyveromyces marxianus; Snf1; Biokemi; Biochemistry; Biokemi; molekylär cellbiologi; Molecular Cellbiology;

   Abstract : Glucose repression is a global regulatory response in the yeast Saccharomyces cerevisiae. Thus, in the presence of glucose, the preferred carbon source, expression of many genes encoding proteins required for metabolism of other carbon sources are turned off.An important mediator of glucose repression is the Mig1 repressor.

7. 5. Extracellular serine proteases as virulence factors in nematophagous fungi: Molecular characterization and functional analysis of the PII protease in Arthrobotrys oligospora

   Author : Johan Åhman; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Aspergillus niger.; Heterologous expression; Over-expression; Gene-disruption; Transformation system; Serine protease; Biological control; Arthrobotrys oligospora; Fungi; Nematophagous; Biologi;

   Abstract : Nematophagous fungi are parasites of nematodes, thus they have been considered and tested for biological control of parasitic nematodes, but so far with limited success. Due to the fact that the nematode cuticle is composed of proteins it is likely that fungal extracellular proteases are involved in the infection of nematodes. READ MORE
