Proton Transport in Metal–Organic Frameworks

Chemical Reviews, 2020
Solid-state proton conductors (SSPCs), which are a key component for the safety and efficiency of fuel cells, have received much attention due to their broad application in electrochemical devices. In particular, the development of new materials with high conducting performance and an understanding of the conduction mechanism have become critical ...

TRANSPORT ATPases IN ANION AND PROTON TRANSPORT

Annals of the New York Academy of Sciences, 1980
Studies in our laboratory have shown that the anion-sensitive Mg-ATPase is located in mitochondria, but not in the plasma membrane of rabbit gastric mucosa, trout gill, rabbit kidney and rat pancreas; whereas in rabbit erythrocyte membrane, it is part of the Ca-Mg activated ATPase system.

Mechanism of proton transport by plant plasma membrane proton ATPases

Journal of Plant Research, 2003
The mechanism of proton translocation by P-type proton ATPases is poorly defined. Asp684 in transmembrane segment M6 of the Arabidopsis thaliana AHA2 plasma membrane P-type proton pump is suggested to act as an essential proton acceptor during proton translocation. Arg655 in transmembrane segment M5 seems to be involved in this proton translocation too,

Theoretical calculation of proton mobility for collective surface proton transport

Physical Review E, 2013
We present a theoretical study of surface proton mobility at a minimally hydrated array of protogenic surface groups. At dense packing, the array assembles into a 2D bicomponent lattice that is formed by sulfonate anions, which are only allowed to fluctuate about fixed equilibrium positions, and mobile hydronium ions.

Proton transport in solids

Journal of Non-Crystalline Solids, 1980
Abstract The proton is the only ion with a negative effective radius. Accordingly its transport by diffusion or electromigration might be expected to show unique features. The literature on proton transport in crystalline solids confirms this expectation.

Proton Solvation and Transport in Hydrated Nafion

The Journal of Physical Chemistry B, 2011
Proton solvation properties and transport mechanisms have been studied in hydrated Nafion using the self-consistent multistate empirical valence bond (SCI-MS-EVB) method that includes the effects excess proton charge defect delocalization and Grotthuss proton hopping.

Proton/Protein Transport

Science, 2001
STRUCTURAL BIOLOGY In eukaryotic cells, F-type ATPases convert a mitochondrial proton gradient into ATP (the final stage in extracting energy from the oxidation of carbon compounds) while V-type ATPases use ATP to transport protons across internal membranes, notably in the acidification of lysosomes.

Proton Transport Pathways in [NiFe]-Hydrogenase

The Journal of Physical Chemistry B, 2012
Hydrogenases reversibly catalyze the production of molecular hydrogen. Current interest in these enzymes is focused on understanding the catalysis, since this may prove useful for hydrogen-based fuel cell and photosynthetic hydrogen production cell technologies.

Proton transport by gastric membrane vesicles

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1977
A highly purified membrane fraction was derived from hog gastric mucosa by a combination of differential and density gradient centrifugation and free flow electrophoresis. This final fraction was 35-fold enriched with respect to cation activated ouabain-insensitive ATPase.
