Zeolite-filled silicone rubber membranes : Part 1. Membrane preparation and pervaporation results [PDF]

open access: yes, 1987
Amongst the alternative fuels obtained from renewable resources alcohol from fermentation may become one of the most important. The combination of fermentation with pervaporation in a membrane bioreactor offers the advantage of continuous processing.

Tonic inhibition of the chloride/proton antiporter ClC-7 by PI(3,5)P2 is crucial for lysosomal pH maintenance

open access: yeseLife, 2022
The acidic luminal pH of lysosomes, maintained within a narrow range, is essential for proper degrative function of the organelle and is generated by the action of a V-type H+ ATPase, but other pathways for ion movement are required to dissipate the ...

Yeast Trk1 Potassium Transporter Gradually Changes Its Affinity in Response to Both External and Internal Signals

open access: yesJournal of Fungi, 2022
Yeasts need a high intracellular concentration of potassium to grow. The main K+ uptake system in Saccharomyces cerevisiae is the Trk1 transporter, a complex protein with four MPM helical membrane motifs.

Oncogenic KRAS mutations enhance amino acid uptake by colorectal cancer cells via the hippo signaling effector YAP1

open access: yesMolecular Oncology, 2021
Oncogenic KRAS mutations develop unique metabolic dependencies on nutrients to support tumor metabolism and cell proliferation. In particular, KRAS mutant cancer cells exploit amino acids (AAs) such as glutamine and leucine, to accelerate energy ...

Transporter-Mediated Drug Delivery

open access: yesMolecules, 2023
Transmembrane transport of small organic and inorganic molecules is one of the cornerstones of cellular metabolism. Among transmembrane transporters, solute carrier (SLC) proteins form the largest, albeit very diverse, superfamily with over 400 members ...

Functional characterization of a highly specific l-arabinose transporter from Trichoderma reesei

open access: yesMicrobial Cell Factories, 2021
Background Lignocellulose biomass has been investigated as a feedstock for second generation biofuels and other value-added products. Some of the processes for biofuel production utilize cellulases and hemicellulases to convert the lignocellulosic ...

TECPR1 promotes aggrephagy by direct recruitment of LC3C autophagosomes to lysosomes

open access: yesNature Communications, 2020
Many neurodegenerative disorders are characterised by the accumulation of protein aggregates in neurons. Here, the authors show that the lysosomal protein TECPR1 selectively recruits mature autophagosomes via an interaction with LC3C to break down ...

The second intracellular loop of the yeast Trk1 potassium transporter is involved in regulation of activity, and interaction with 14–3-3 proteins

open access: yesComputational and Structural Biotechnology Journal, 2023
Potassium is an essential intracellular ion, and a sufficient intracellular concentration of it is crucial for many processes; therefore it is fundamental for cells to precisely regulate K+ uptake and efflux through the plasma membrane.
