Halide-selective, proton-coupled anion transport by phenylthiosemicarbazones [PDF]

, 2021
Phenylthiosemicarbazones (PTSCs) are proton-coupled anion transporters with pH-switchable behaviour known to be regulated by an imine protonation equilibrium.

The sodium-dependent D-glucose transport protein of Helicobacter pylori [PDF]

, 2008
Helicobacter pylori is a gram-negative pathogenic microaerophile with a particular tropism for the mucosal surface of the gastric epithelium. Despite its obligatory microaerophilic character, it can metabolize D-glucose and/or D-galactose in both ...

Sodium and proton transport in Mycoplasma gallisepticum [PDF]

Journal of Bacteriology, 1985
When washed cells of Mycoplasma gallisepticum were incubated at 37 degrees C in 250 mM 22NaCl, the intracellular Na+ increased, and the K+ decreased. The addition of glucose to these Na+-loaded cells caused Na+ efflux and K+ uptake (both ions moving against concentration gradients).

Structures in multiple conformations reveal distinct transition metal and proton pathways in an Nramp transporter

eLife, 2019
Nramp family transporters—expressed in organisms from bacteria to humans—enable uptake of essential divalent transition metals via an alternating-access mechanism that also involves proton transport.

Electron and proton transport by NADPH oxidases [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2005
The NADPH oxidase is the main weapon of phagocytic white blood cells that are the first line of defence of our body against invading pathogens, and patients lacking a functional oxidase suffer from severe and recurrent infections. The oxidase is a multisubunit enzyme complex that transports electrons from cytoplasmic NADPH to molecular oxygen in order ...
