The basic problem is one of prior knowledge. The information you have about E. coli metabolism is in the form of a simple network, i.e. a list of nodes and the edges (along with their weights) that connect them. From this information alone it's impossible to know, for example, that the reactions in the TCA cycle should be plotted as a perfect circle (that's ...

In Gastrointestinal Tract Location of Escherichia coli O157:H7 in Ruminants (Grauke et al. 2002): in the lower GIT digesta, specifically the cecum, colon It's about O157:H7, but I think the standard act a same.

E.coli strains that have dam or dcm methylases can methylate plasmid at adenines or cytosines respectively. See here — It is a NEB web page but has links to the cited references. DH5α has both the methylases- dam+ dcm+ , BL21 is dam+ dcm− and ET12567 is dam− dcm−

I'm not sure if they will be useful for your application, but you should look into software used to visualize ecological networks (and maybe also software used for drawing electrical charts). The type of data used there is very similar to what you want to plot, with nodes and links along with metadata for links on e.g. rates or connection strenghts. I can ...

It is not uncommon for cells to have parallel pathways for same outcome. This ensures foolproof response and makes the system robust. E.coli also has another sensor for aerotaxis (Aer and Tsr proteins). See my answer on your previous post and the linked paper. Also look for coherent feed forward network motifs.

Non-coding transcripts can be as small as 10-15 nucleotides. Once the RNA polymerase initiates, the DNA is melted and the transcription bubble forms. This region is about 10 nucleotides long. But if you are asking the limit of mRNA length, then the answer is different. First of all, to get a protein, the ribosomes have to translate the transcript. To do ...
