uhp-directed, glucose 6-phosphate membrane receptor in Escherichia coli.
Membrane vesicles were characterized for their ability to specifically bind [14C]glucose 6-phosphate. Membranes prepared from a strain carrying a ColE1 uhp hybrid plasmid showed significantly enhanced glucose 6-phosphate binding. It is hypothesized that glucose 6-phosphate binding to these membranes is due to a uhpR-directed, membrane-bound receptor which functions in regulation of the inducibl...
متن کاملAccumulation of glucose 6-phosphate or fructose 6-phosphate is responsible for destabilization of glucose transporter mRNA in Escherichia coli.
Previously we found that a mutation in either pgi or pfkA, encoding phosphoglucose isomerase or phosphofructokinase A, respectively, facilitates degradation of the ptsG mRNA in an RNase E-dependent manner in Escherichia coli (1). In this study, we examined the effects of a series of glycolytic genes on the degradation of ptsG mRNA and how the mutations destabilize the ptsG mRNA. The conditional...
متن کاملThe accumulation of glucose 6-phosphate from glucose and its effect in an Escherichia coli mutant lacking phosphoglucose isomerase and glucose 6-phosphate dehydrogenase.
When presented with glucose, an Escherichia coli mutant lacking both phosphoglucose isomerase and glucose 6-phosphate dehydrogenase accumulated, internally, high concentrations (approximately 50 mM) of glucose 6-phosphate. It also accumulated glucose in polysaccharide form. Other metabolism of glucose, if any, was very restricted. The accumulation of glucose 6-phosphate was associated with inhi...
متن کاملGlucose-6-phosphate-dependent phosphoryl flow through the Uhp two-component regulatory system.
Expression of the UhpT sugar-phosphate transporter in Escherichia coli is regulated at the transcriptional level via the UhpABC signalling cascade. Sensing of extracellular glucose 6-phosphate (G6P), by membrane-bound UhpC, modulates a second membrane-bound protein, UhpB, resulting in autophosphorylation of a conserved histidine residue in the cytoplasmic (transmitter) domain of the latter. Sub...
متن کاملCatabolite repression by glucose 6-phosphate, gluconate and lactose in Escherichia coli.
While catabolite repression by glucose has been studied extensively and is understood in large detail in Enterobacteriaceae, catabolite repression by carbohydrates that are not transported by the phosphotransferase system (PTS) has always remained an enigma. Examples of non-PTS carbohydrates that cause catabolite repression in Escherichia coli are gluconate, lactose and glucose 6-phosphate. In ...
