Project description:Escherichia coli (E. coli) amine oxidase (ECAO) encoded by tynA gene has been one of the model enzymes to study the mechanism of oxidative deamination of amines to the corresponding aldehydes by amine oxidases. The biological roles of ECAO have been less addressed. Therefore we have constructed a gene deletion Escherichia coli K-12 strain, E. coli tynA-, and used the microarray technique to address its function by comparing the total RNA gene expression to the one of the wt. Our results suggest that tynA is a reserve gene for stringent environmental conditions and its gene product ECAO a growth advantage compared to other bacteria due to H2O2 production.
Project description:Transcripitonal profiling of Escherichia coli K-12 W3110 comparing cells with and without hydrogen peroxide treatment, two biological replicates each
Project description:E. coli K-12 ATCC 25404 in LB medium with 5-fluorouracil 10 uM biofilm cells relative to E. coli K-12 ATCC 25404 in LB DMF biofilm cells. The same amount of stock 5-fluoroacil stock solution (0.1% of the volume) was added as DMF into the LB DMF.
Project description:Transcripitonal profiling of Escherichia coli K-12 BW25113 comparing cells with isooctane treatment at time point of 0, 10, 30 and 60 min with two biological replicates
Project description:Sequencing reads of Escherichia coli K-12 control and antibiotic-treated cultures enriched (Cappable-Seq) and not enriched (Ultra directional) for the 5’ end of primary transcripts.
Project description:The transcriptome of Escherichia coli K-12 has been widely studied over a variety of conditions for the past decade while such studies involving E. coli O157:H7, its pathogenic cousin, are just now being conducted. To better understand the impact of intracellular life within a ruminant and environmental protozoan on E. coli O157:H7, global transcript levels of strain EDL933 cells inside Acanthamoeba were compared to cell grown in the protozoan media (ATCC PYG712) by microarray.
