Conserved Residues R420 and Q428 in a Cytoplasmic Loop of the Citrate/Malate Transporter CimH of Bacillus subtilis Are Accessible from the External Face of the Membrane [PDF]
, 2003 CimH of Bacillus subtilis is a secondary transporter for citrate and malate that belongs to the 2-hydroxycarboxylate transporter (2HCT) family. Conserved residues R143, R420, and Q428, located in putative cytoplasmic loops and R432, located at the ...

Scientific Reports, 2021 Bile acid sodium symporter (BASS) family proteins encode a class of sodium/solute symporters. Even though the sodium transporting property of BASSs in mammals was well studied, their sodium transportability and functional roles in plant salt tolerance ...

Dimerization of the Sodium/Iodide Symporter
Thyroid, 2019 Background: The ability of thyroid follicular epithelial cells to accumulate iodide via the sodium/iodide symporter (NIS) is exploited to successfully treat most thyroid cancers, although a subset of patients lose functional NIS activity and become unresponsive to radioiodide therapy, with poor clinical outcome.

Co-transport-induced instability of membrane voltage in tip-growing cells [PDF]
Phys. Rev. Lett. 95 (2005) 208105, 2005 A salient feature of stationary patterns in tip-growing cells is the key role played by the symports and antiports, membrane proteins that translocate two ionic species at the same time. It is shown that these co-transporters destabilize generically the membrane voltage if the two translocated ions diffuse differently and carry a charge of opposite ...

Conformational transitions of the sodium-dependent sugar transporter, vSGLT. [PDF]
, 2018 Sodium-dependent transporters couple the flow of Na+ ions down their electrochemical potential gradient to the uphill transport of various ligands. Many of these transporters share a common core structure composed of a five-helix inverted repeat and ...

New Choice for Small Universal Devices: Symport/Antiport P Systems [PDF]
EPTCS 1, 2009, pp. 235-242, 2009 Symport/antiport P systems provide a very simple machinery inspired by corresponding operations in the living cell. It turns out that systems of small descriptional complexity are needed to achieve the universality by these systems. This makes them a good candidate for small universal devices replacing register machines for different simulations ...

Transition metal ion FRET uncovers K+ regulation of a neurotransmitter/sodium symporter
Nature Communications, 2016 The neurotransmitter transporter SERT counter transport K+ to transport serotonin. Here the authors show that the activity of the prokaryotic orthologue LeuT is also modulated by this cation, suggesting a general regulatory role for K+on neutrotrasmitter:

Evolutionary ancestry and novel functions of the mammalian glucose transporter (GLUT) family
BMC Evolutionary Biology, 2010 Background In general, sugar porters function by proton-coupled symport or facilitative transport modes. Symporters, coupled to electrochemical energy, transport nutrients against a substrate gradient.
