The conserved carboxy-terminal region of the ammonia channel AmtB plays a critical role in channel function
The ammonium transport (Amt) proteins are a highly conserved family of integral membrane proteins found in eubacteria, archaea, fungi and plants. Genetic, biochemical and bioinformatic analyses… Expand

Ammonium Sensing in Escherichia coli
The Amt proteins are high affinity ammonium transporters that are conserved in all domains of life. In bacteria and archaea the Amt structural genes (amtB) are invariably linked to glnK, which… Expand

In vivo functional characterization of the Escherichia coli ammonium channel AmtB: evidence for metabolic coupling of AmtB to glutamine synthetase.
The Escherichia coli AmtB protein is member of the ubiquitous Amt family of ammonium transporters. Using a variety of [14C]methylammonium-uptake assays in wild-type E. coli, together with amtB and… Expand

An Unusual Twin-His Arrangement in the Pore of Ammonia Channels Is Essential for Substrate Conductance*
Amt proteins constitute a class of ubiquitous integral membrane proteins that mediate movement of ammonium across cell membranes. They are homotrimers, in which each subunit contains a narrow pore… Expand

Transport mechanisms in the ammonium transporter family.
Ammonium transport is mediated by membrane proteins of the ubiquitous Amt/Rh family. Despite the availability of different X-ray structures that provide many insights on the ammonium permeation… Expand

The Escherichia coli SLC26 homologue YchM (DauA) is a C4‐dicarboxylic acid transporter
The SLC26/SulP (solute carrier/sulphate transporter) proteins are a ubiquitous superfamily of secondary anion transporters. Prior studies have focused almost exclusively on eukaryotic members and… Expand

Complex formation between AmtB and GlnK: an ancestral role in prokaryotic nitrogen control.
Ammonium transport proteins belonging to the Amt family are ubiquitous in prokaryotes. In Escherichia coli, the AmtB protein and the associated P(II) signal transduction protein (GlnK) have recently… Expand

Low Resolution Structure of a Bacterial SLC26 Transporter Reveals Dimeric Stoichiometry and Mobile Intracellular Domains*
The SLC26/SulP (solute carrier/sulfate transporter) proteins are a superfamily of anion transporters conserved from bacteria to man, of which four have been identified in human diseases. Proteins… Expand

An update on nutrient transport processes in ectomycorrhizas
Nutrient transport, namely absorption from the soil solution as well as nutrient transfer from fungus to plant and carbon movement from plant to fungus are key features of mycorrhizal symbiosis. This… Expand

The lipid environment determines the activity of the Escherichia coli ammonium transporter AmtB
The movement of ammonium across biologic membranes is a fundamental process in all living organisms and is mediated by the ubiquitous ammonium transporter/methylammonium permease/rhesus protein… Expand
