Modeling of SGLT1 in Reconstituted Systems Reveals Apparent Ion-Dependencies of Glucose Uptake and Strengthens the Notion of Water-Permeable Apo States

open access: yesFrontiers in Physiology, 2022
The reconstitution of secondary active transporters into liposomes shed light on their molecular transport mechanism. The latter are either symporters, antiporters or exchangers, which use the energy contained in the electrochemical gradient of ions to ...

A partially-open inward-facing intermediate conformation of LeuT is associated with Na+ release and substrate transport

open access: yesNature Communications, 2018
Neurotransmitter:sodium symporters (NSS) modulate the duration and magnitude of signaling via the sodium-coupled reuptake of neurotransmitters. Here the authors describe quantitative single molecule imaging of ligand-induced, functional dynamics of both ...

Allosterically Linked Binding Sites in Serotonin Transporter Revealed by Single Molecule Force Spectroscopy

open access: yesFrontiers in Molecular Biosciences, 2020
Crystal structures and experiments relying on the tools of molecular pharmacology reported conflicting results on ligand binding sites in neurotransmitter/sodium symporters (NSS). We explored the number and functionality of ligand binding sites of NSS in

Monosaccharide transporters in plants: structure, function and physiology [PDF]

open access: yes, 2000
Monosaccharide transport across the plant plasma membrane plays an important role both in lower and higher plants. Algae can switch between phototrophic and heterotrophic growth and utilize organic compounds, such as monosaccharides as additional or sole

Proteomics: in pursuit of effective traumatic brain injury therapeutics [PDF]

open access: yes, 2015
Effective traumatic brain injury (TBI) therapeutics remain stubbornly elusive. Efforts in the field have been challenged by the heterogeneity of clinical TBI, with greater complexity among underlying molecular phenotypes than initially conceived.

A conserved leucine occupies the empty substrate site of LeuT in the Na+-free return state

open access: yesNature Communications, 2016
Neurotransmitter:sodium symporters (NSS) perform Na+-dependent amino-acid uptake, but a full structural description of their function is lacking. Here the authors present a structure of the bacterial NSS LeuT in the outward-oriented empty state and show ...

Two glycerol uptake systems contribute to the high osmotolerance of Zygosaccharomyces rouxii [PDF]

open access: yes, 2015
The accumulation of glycerol is essential for yeast viability upon hyperosmotic stress. Here we show that the osmotolerant yeast Zygosaccharomyces rouxii has two genes, ZrSTL1 and ZrSTL2, encoding transporters mediating the active uptake of glycerol in ...

Effect of Dimerization on the Dynamics of Neurotransmitter:Sodium Symporters

open access: yesThe Journal of Physical Chemistry B, 2017
Dimerization is a common feature among the members of the neurotransmitter:sodium symporter (NSS) family of membrane proteins. Yet, the effect of dimerization on the mechanism of action of NSS members is not fully understood. In this study, we examined the collective dynamics of two members of the family, leucine transporter (LeuT) and dopamine ...

Metabolic Profiles of Carbohydrates in Streptococcus thermophilus During pH-Controlled Batch Fermentation

open access: yesFrontiers in Microbiology, 2020
Revealing the metabolic profiles of carbohydrates with their regulatory genes and metabolites is conducive to understanding their mechanism of utilization in Streptococcus thermophilus MN-ZLW-002 during pH-controlled batch fermentation.

Gating Topology of the Proton-Coupled Oligopeptide Symporters [PDF]

open access: yesStructure, 2015
Proton-coupled oligopeptide transporters belong to the major facilitator superfamily (MFS) of membrane transporters. Recent crystal structures suggest the MFS fold facilitates transport through rearrangement of their two six-helix bundles around a central ligand binding site; how this is achieved, however, is poorly understood.
