The molecular basis of K+ exclusion by the Escherichia coli ammonium channel AmtB.

The Journal of biological chemistry - 17 May 2013

Hall Jason A, Yan Dalai

Abstract excerpt

Members of the Amt family of channels mediate the transport of ammonium. The form of ammonium, NH3 or NH4(+), carried by these proteins remains controversial, and the mechanism by which they select against K(+) ions is unclear. We describe here a set of Escherichia coli AmtB proteins carrying mutations at the conserved twin-histidine site within the conduction pore that have altered substrate specificity and now...
