Technology type: Initial Rate Experiment
Investigation: The Attic
L. lactis, E. faecalis and S. pyogenes are referred to as LAB because of the fact that in the presence of glucose lactate is produced as the main fermentation product . This metabolic pathway is relatively inefficient, since only 2 ATP are generated from one glucose molecule. All three LAB possess the genetic make up for mixed acid fermentation, a more effective way of fermentation generating 3 ATP per molecule of glucose. All three genomes reveal (at least) two genes encoding a lactate dehydrogenase ...

Cells were grown to mid-exponential phase (OD600nm ~0.2) in GM17 medium at 37°C (with 0.15 mM ZnSO4 where relevant) and 84 ml of culture was mixed by inverting with 8.4 ml of fixing solution (50 mM Tris pH 8.0, 100 mM NaCl, 0.5 mM EGTA, 1 mM EDTA, 30% (v/v) formaldehyde) and incubated at room temperature for 30 min. Cells were disrupted and crosslinked DNA was sheared by sonication. Antibodies coupled to magnetic beads were used to pull down cross-linked complexes. DNA was purified, amplified, ...

Artificial transcription elongation compexes are assembled in vitro using synthetic deoxy-oligonucleotides (representing template and non template DNA strands), radiolabelled RNA (representing nascent transcript) and purified RNA polymerase. After high salt wash the incorrect NTP is added and reaction is allowed to proceed for the various amounts of time. Reaction is stopped by addition of formamide-containing loading solution and the products are resolved on high-percentage denaturing polyacryamide ...

For analyzing the binding of CcpA-HPrSer46P-complexes to various cre-elements, Surface Plasmon Resonance was used. All operations were carried out on a Biacore X instrument (Biacore, Uppsala, Sweden). Biotinylated cre DNA was coupled on a Neutravidin coated chip in flowcell two, a biotinylated reference DNA in flowcell one. For visualizing only the interactions of the CcpA-HPrSer46P-complex with the cre elements, CcpA was saturated with 50µM HPrSer46P. Titrations were carried out with 5-100nM ...

S.pneumoniae D39 cells (wild type and delta greA) were grown in C+Y medium and cells were harvested for total RNA isolation at mid-exponential growth (OD600nm 0.3 for wt, 0.25 for delta greA). Total RNA was isolated as described before (Kloosterman et al 2006). The total RNA samples were examined by capillary electrophoresis. dephosphorylated with antarctic phosphatase followed by treatment with polynucleotide kinase (PNK). Afterwards, samples were poly(A)-tailed using poly(A) polymerase. Then a ...

Some examples of transcriptomics templates for Affymetrix data that conform to the MAGE-TAB specification. These templates were taken from the GEO website (http://www.ncbi.nlm.nih.gov/geo/info/spreadsheet.html) and modified to conform to the SysMO-JERM (Just enough Results Model) for transcriptomics. Using these templates will mean easier submission to GEO/ArrayExpress and greater consistency of data in SEEK.

This assay is designed to measure the decay kinetics of mRNA in T. brucei blood forms. T. brucei lacks the canonical transcriptional regulation employed by other eukaryotes through transcription factors, and relies almost entirely on regulation of mRNA decay and further downstream steps in order to control gene expression. 3 replicates of 8 time points were taken to measure mRNA abundance in the cell using RNA-seq. The first time point was fot WT, untreated cells; the second was 5 min after the ...
