A chemiosmotic mechanism of symport [PDF]
Proceedings of the National Academy of Sciences, 2015 Lactose permease (LacY), a paradigm for the largest family of membrane transport proteins, catalyzes the coupled translocation of a galactoside and an H + across the Escherichia coli membrane (galactoside/H + symport).

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 ...

About P systems with symport/antiport [PDF]
Soft Computing, 2004 It is proved that four membranes su±ce to P systems with minimal symport/antiport to generate all recursively enumerable sets of numbers. It is also proved that P systems with symport/antiport without maximal par- allelism are equivalent to partially blind counter automata.

Light-induced transcriptional responses associated with proteorhodopsin-enhanced growth in a marine flavobacterium [PDF]
, 2011 Proteorhodopsin (PR) is a photoprotein that functions as a light-driven proton pump in diverse marine Bacteria and Archaea. Recent studies have suggested that PR may enhance both growth rate and yield in some flavobacteria when grown under nutrient ...

Molecular determinants for the thermodynamic and functional divergence of uniporter GLUT1 and proton symporter XylE. [PDF]
PLoS Computational Biology, 2017 GLUT1 facilitates the down-gradient translocation of D-glucose across cell membrane in mammals. XylE, an Escherichia coli homolog of GLUT1, utilizes proton gradient as an energy source to drive uphill D-xylose transport.
