What is a Study?Filters
The aim of the study is to test the interplay of the effects of different transcriptional regulators on gene expression during different environmental responses in B. subtilis. For a selected set of transcriptional regulators native proteins are fusion-labelled. The intensity of expression of each reporter protein is measured in the absence of several transcriptional regulators that compete for the RNA polymerase.
B. subtilis was grown in minimal media in a chemostat at different growth rates (µ= max, µ=0.1, µ=0.4) and in the presence of 1.2M NaCl (µ=0.1) with or without glycinebetaine. Transcriptome, proteome and metabolome were investigated.

Assays: Absolute quantification of proteins by the AQUA-technology, Absolute quantification of proteins using QconCAT technology, Relative quantification of proteins by metabolic labeling, Transcriptome data for chemostat cultivated samples, extracellular metabolites, intracellular metabolites
Goals:
- Understanding the regulatory principles of Escherichia coli’s electron transport chain (ETC) for varying oxygen conditions in glucose-limited continuous cultures (especially regulatory loops via the transcription factors FNR and ArcA).
- Explaining the observed phenomena in the measurement data.
- Predicting unmeasured variables especially of the gene expression regulatory loops.
Means:
- Experiments (chemostat experiments within the aerobiosis scale).
- Kinetic modelling (especially ...
The main aim of this experiment is to actively grow B.subtilis in presense of glucose until high optical density in an aerobic fermentor and then, at a definite point of the growth, the glucose supply is shut down which leads to complete glucose exhaustion in the media. Simultaneusly samples for transcriptomics, intra and extracellular metabolomics, intra and extracellular proteomics are harvested through out the experiment.
