Direct observation of electrogenic NH 4 + transport in ammonium transport (Amt) proteins

Proceedings of the National Academy of Sciences of the United States of America, 2014
Ammonium transport (Amt) proteins form a ubiquitous family of integral membrane proteins that specifically shuttle ammonium across membranes. In prokaryotes, archaea, and plants, Amts are used as environmental NH4(+) scavengers for uptake and ...

The MATE proteins as fundamental transporters of metabolic and xenobiotic organic cations

Trends in Pharmacological Sciences, 2006
Multidrug and toxic compound extrusion (MATE) proteins, comprising the most recently designated family of multidrug transporter proteins, are widely distributed in all kingdoms of living organisms, although their function is far from understood. The bacterial MATE-type transporters that have been characterized function as exporters of cationic drugs ...

Differential interaction of cations with the thiamine and biotin transport proteins of Lactobacillus casei

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1985
Lactobacillus casei cells contain separate and specific binding proteins which mediate the cellular uptake of thiamine and biotin. In buffered salt solutions, these proteins exhibit a very high affinity for their vitamin substrate. Dissociation constants (Kd values) at pH 7.5 are 0.03 and 0.15 nM for thiamine and biotin, respectively.

Transport of asymmetric dimethylarginine (ADMA) by cationic amino acid transporter 2 (CAT2), organic cation transporter 2 (OCT2) and multidrug and toxin extrusion protein 1 (MATE1)

Amino Acids, 2013
Asymmetric dimethylarginine (ADMA), inhibiting the nitric oxide (NO) synthesis from L-arginine, is a known cardiovascular risk factor. Our aim was to investigate if ADMA and/or L-arginine are substrates of the human cationic amino acid transporters 2A (CAT2A, SLC7A2A) and 2B (CAT2B, SLC7A2B), the organic cation transporter 2 (OCT2, SLC22A2), and the ...

Peptide models for protein-mediated cation transport

Canadian Journal of Biochemistry, 1980
Substances which can perturb the transmembrane cation balance in a predictable manner have wide-ranging uses in the study of cellular processes. We have undertaken to examine transmembrane calcium transport on the molecular level through the design and synthesis of a series of ionophoric peptides as models for protein-mediated calcium transport ...

Protein partitioning and transport in supported cationic acrylamide‐based hydrogels

AIChE Journal, 2003
AbstractThe partitioning and transport of myoglobin in cationic, acrylamide‐based hydrogels are studied by a microscopic visualization method. Homogeneous cationic gels are synthesized inside fused‐silica capillaries with a square section, which allow a direct determination of protein concentration profiles during transient adsorption and desorption ...
