Kinetics of exogenous induction of the hexose-6-phosphate transport system of Escherichia coli

H H Winkler. J Bacteriol. 1971 Jul.

Abstract

The kinetics of the exogenous induction of the hexose-phosphate transport system by glucose-6-phosphate (G6P) was investigated. The induction of this system by extracellular but not intracellular G6P was confirmed. The differential rate of synthesis was linear, a function of the extracellular concentration of G6P and independent of the previous induction history of the culture. Neither maintenance nor autocatalysis, phenomena described in the induction of the lac operon, were observed in the exogenous induction of hexose-phosphate transport. Fructose-6-phosphate, a potent competitive inhibitor of G6P influx, had no effect on the induction of the system by G6P, indicating that the transport of inducer was not involved in the induction process.
