Genetic analysis of potassium transport loci in Escherichia coli: evidence for three constitutive systems mediating uptake potassium.

Journal of bacteriology - 1 Jan 1991

Dosch D C, Helmer G L, Sutton S H, Salvacion F F, Epstein W

Abstract excerpt

The analysis of mutants of Escherichia coli that require elevated concentrations of K+ for growth has revealed two new genes, trkG, near minute 30 within the cryptic rac prophage, and trkH, near minute 87, the products of which affect constitutive K+ transport. The analysis of these and other trk mutations suggests that high rates of transport, previously considered to represent the activity of a single system,...
