Glucose Transport and Transporters in the Endomembranes [PDF]
International Journal of Molecular Sciences, 2019 Glucose is a basic nutrient in most of the creatures; its transport through biological membranes is an absolute requirement of life. This role is fulfilled by glucose transporters, mediating the transport of glucose by facilitated diffusion or by secondary active transport.

Transport and transporters in the endoplasmic reticulum
Biochimica et Biophysica Acta (BBA) - Biomembranes, 2007 Enzyme activities localized in the luminal compartment of the endoplasmic reticulum are integrated into the cellular metabolism by transmembrane fluxes of their substrates, products and/or cofactors. Most compounds involved are bulky, polar or even charged; hence, they cannot be expected to diffuse through lipid bilayers.

Nitrate transporters and peptide transporters
FEBS Letters, 2007 In higher plants, two types of nitrate transporters, NRT1 and NRT2, have been identified. In Arabidopsis, there are 53 NRT1 genes and 7 NRT2 genes. NRT2 are high‐affinity nitrate transporters, while most members of the NRT1 family are low‐affinity nitrate transporters.

Transport Dynamics in a Glutamate Transporter Homologue [PDF]
Biophysical Journal, 2013 Glutamate transporters are integral membrane proteins that catalyse neurotransmitter uptake from the synaptic cleft into the cytoplasm of glial cells and neurons. Their mechanism of action involves transitions between extracellular (outward)-facing and intracellular (inward)-facing conformations, whereby substrate binding sites become accessible to ...
