Vanillin Resistance Induced by BssS Overexpression in Escherichia coli
Overexpression of the BssS gene, a biofilm formation regulator, in planktonic Escherichia coli cells has been shown to confer the vanillin-resistant phenotype Vanr to the bacteria. The MG1655PL-tac-bssS strain st...

Comparative Analysis of Mono- and Bifunctional Chorismate Synthases in Escherichia coli Cells Capable and Incapable of Phenylalanine Production
The activity of chorismate synthase, the terminal enzyme of the common aromatic pathway, is absolutely dependent on reduced flavin mononucleotide. The bifunctional chorismate synthase of Saccharomyces cerevisiae ...

Gene yddG of Escherichia coli encoding the putative exporter of aromatic amino acids: Constitutive transcription and dependence of the expression on the cell growth rate
Gene yddG of Escherichia coli encodes a protein of the inner membrane. Data obtained earlier demonstrated that under conditions of aromatic amino acids overproduction YddG promotes their export from E. coli cells...

2D [1H,13C] NMR study of carbon fluxes during glucose utilization by Escherichia coli MG1655
Carbon fluxes through main pathways of glucose utilization in Escherichia coli cells-glycolysis, pentose phosphate pathway (PPP), and Enther-Doudoroff pathway (EDP)—were studied. Their ratios were analyzed in E. ...

Tuning the Expression Level of a Gene Located on a Bacterial Chromosome
A new method of constructing a set of bacterial cell clones varying in the strength of a promoter upstream of the gene of interest was developed with the use of Escherichia coli MG1655 and lacZ as a reporter. The...
