A new cellular transport mechanism splits the substrate and separately translocates its fragments to achieve selectivity.

Two thermodynamically distinct transport mechanisms operating within the same binding site explains the remarkable promiscuity of POT family transporters towards peptide and drug ligands.

Crystal structures of the mouse CMP-sialic acid transporter in complex with both CMP and CMP-sialic acid reveal the mechanisms of substrate selectivity and transport.

To avoid internal traffic jams of nutrients that they absorb, plants need to swiftly regulate the transporters that take up those nutrients.

Efficient nuclear transport of very large biomolecules, relevant for viral transport, scales non-linearly with size and its kinetics can be explained by a simple two-parameter energetic model.

Nramp-family transporters adapt a common fold to a novel mechanism in which the spatial and temporal separation of like-charge transition metal and proton co-substrates circumvents the expected electrostatic repulsion.

The cryo-EM structure and functional characterization of the chloride-selective ion transporter Slc26a9 defines its oligomeric architecture and transport mechanism.

Peptide and nitrate transporters have been converted into fluorescent reporters of transport activity and have been used to measure various transport properties including the dual affinity of the nitrate transceptor

A transport mechanism is uncovered in the major drug-efflux system in E. coli involving two remote alternating-access conformational cycles, which could provide the basis for the development of allosteric inhibitors against multidrug resistance.

Crystal structures of an archaeal homologue of mammalian glutamate transporters in apo and ion-only bound outward- and inward-facing states reveal ion-coupled conformational changes supporting mechanisms of coupling, gating, and transport.
