Kup is the major K+ uptake system in Escherichia coli upon hyper-osmotic stress at a low pH.

FEBS letters - 26 Mar 1999

Trchounian A, Kobayashi H

Abstract excerpt

The K+ uptake was observed in washed cells of Escherichia coli, wild-type, upon hyper-osmotic stress at pH 5.5 when glucose was supplemented. This uptake had apparent a Km of 0.58 mM and Vmax of 0.10 micromol K+/min/mg protein. Such a K+ uptake was investigated using a mutant defective in Kdp and TrkA but with a functional Kup and a mutant defective in Kdp and Kup but having an active TrkA. The K+ uptake to reach...
