Structural, functional and mechanistic analysis of the Escherichia coli ammonium transporter AmtB
The exchange of ammonium across cellular membranes is an essential process in all kingdoms of life. Ammonium is a major source of nitrogen for bacteria, fungi, and plants, whereas in animal cells it is a cytotoxic waste metabolite, which must be excreted. The transport of ammonium is accomplished …

Genetic and biochemical analysis of nitrogen metabolism in ruminal anaerobic bacteria: a comparison between ruminococcus albus 8 and prevotella ruminicola 23
… late exponential phase. During this phase an ammonium transporter was also up-regulated, apparently as an attempt to enhance ammonia uptake from the medium as the ammonia concentration became low (< 1 mM). Three different types of GS from P. ruminicola 23 were heterologously expressed in E. …

The Role of Urease in the Pathogenesis of Edwardsiella ictaluri
… included ureE, ureF, ureG, ureD, ureI, and an ammonium transporter homologue. The ureG gene encodes a GTP-binding accessory protein which is thought to function in energy-dependent urease assembly. The ureG mutant strain was found to be attenuated for mortality, persistence, and for the ability …

Monte Carlo Simulation Methods for Studying the Thermodynamics of Ligand Binding & Transfer Processes in Biomolecules
… the thermodynamics of transport through the ammonium transporter Amt-1 from Archaeoglobus fulgidus (AfAmt-1). Ammonium is the most directly utilizable nitrogen source for plants and microorganisms. AfAmt-1 and its homologues facilitate the transport of ammonia/ammonium across biological …

Nitrate and ammonium interactions in maize.
… its growth and development. Nitrate (NO₃⁻) and ammonium (NH₄⁺) are the predominant forms of N available to plants in agricultural soils. Plants have the ability to absorb both these forms efficiently from the soil solutions. With soil solution concentrations of NH₄⁺ being much lower (on average …
