Protein phylogenetic analysis of Ca2+/cation antiporters and insights into their evolution in plants

open access: yesFrontiers in Plant Science, 2012
Cation transport is a critical process in all organisms and is essential for mineral nutrition, ion stress tolerance, and signal transduction. Transporters that are members of the Ca2+/Cation Antiporter (CaCA) superfamily are involved in the transport of

Quantitative description of ion transport via plasma membrane of yeast and small cells [PDF]

open access: yes, 2015
Modeling of ion transport via plasma membrane needs identification and quantitative understanding of the involved processes. Brief characterization of main ion transport systems of a yeast cell (Pma1, Ena1, TOK1, Nha1, Trk1, Trk2, non-selective cation ...

Prediction of membrane transport proteins and their substrate specificities using primary sequence information. [PDF]

open access: yesPLoS ONE, 2014
Membrane transport proteins (transporters) move hydrophilic substrates across hydrophobic membranes and play vital roles in most cellular functions. Transporters represent a diverse group of proteins that differ in topology, energy coupling mechanism ...

The Potassium Transporter Hak1 in Candida Albicans, Regulation and Physiological Effects at Limiting Potassium and under Acidic Conditions

open access: yesJournal of Fungi, 2021
The three families of yeast plasma membrane potassium influx transporters are represented in Candida albicans: Trk, Acu, and Hak proteins. Hak transporters work as K+-H+ symporters, and the genes coding for Hak proteins are transcriptionally activated ...

Purification and Reconstitution of the Glutamate Carrier GltT of the Thermophilic Bacterium Bacillus stearothermophilus [PDF]

open access: yes, 1995
An affinity tag consisting of six adjacent histidine residues followed by an enterokinase cleavage site was genetically engineered at the N-terminus of the glutamate transport protein GltT of the thermophilic bacterium Bacillus stearothermophilus.

The ins and outs of metal homeostasis by the root nodule actinobacterium Frankia [PDF]

open access: yes, 2014
Background: Frankia are actinobacteria that form a symbiotic nitrogen-fixing association with actinorhizal plants, and play a significant role in actinorhizal plant colonization of metal contaminated areas.

The functions of plant cation/proton antiporters

open access: yesBiologia Plantarum, 2018
The cation/H+ exchange is a basic process in transmembrane transport. The acquisition of genome sequences has now established that plants possess genes encoding a large number of cation/proton antiporter 1 (CPA1) proteins, few of which have been ...

Claudins in the Renal Collecting Duct [PDF]

open access: yes, 2019
The renal collecting duct fine-tunes urinary composition, and thereby, coordinates key physiological processes, such as volume/blood pressure regulation, electrolyte-free water reabsorption, and acid-base homeostasis.

Determinants of cation transport selectivity: Equilibrium binding and transport kinetics

open access: yesThe Journal of General Physiology, 2015
The crystal structures of channels and transporters reveal the chemical nature of ion-binding sites and, thereby, constrain mechanistic models for their transport processes.
