Effect of sugar transporter on galactose utilization in Streptococcus thermophilus [PDF]
Frontiers in Microbiology, 2023 IntroductionStreptococcus thermophilus is a traditional starter for dairy products. The lactose rich in milk is the main carbon source for the growth of S. thermophilus. However, the utilization of galactose by S.

Lactose Permease Scrambles Phospholipids
Biology, 2023 Lactose permease (LacY) from Escherichia coli belongs to the major facilitator superfamily. It facilitates the co-transport of β-galactosides, including lactose, into cells by using a proton gradient towards the cell.

Characterization of new polyol/H+ symporters in Debaryomyces hansenii. [PDF]
PLoS ONE, 2014 Debaryomyces hansenii is a halotolerant yeast that produces and assimilates a wide variety of polyols. In this work we evaluate polyol transport in D. hansenii CBS 767, detecting the occurrence of polyol/H(+) (and sugar/H(+)) symporter activity, through ...

ZrFsy1, a high-affinity fructose/H+ symporter from fructophilic yeast Zygosaccharomyces rouxii. [PDF]
PLoS ONE, 2013 Zygosaccharomyces rouxii is a fructophilic yeast than can grow at very high sugar concentrations. We have identified an ORF encoding a putative fructose/H(+) symporter in the Z. rouxii CBS 732 genome database.

Equilibrium Properties of E. coli Lactose Permease Symport -- A Random-walk Model Approach [PDF]
, 2021 The symport of lactose and H+ is an important physiological process in E. coli, for it is closely related to cellular energy supply. In this paper, the symport of H+ and lactose by E. coli LacY protein is computationally simulated using a newly proposed cotransport model that takes the "leakage" phenomenon (uncoupled sugar translocation) into account ...

Structural basis for proton coupled cystine transport by cystinosin
Nature Communications, 2022 Mutations in CTNS, the lysosomal cystine-proton symporter, cause cystinosis. Here authors report crystal structures of CTNS from Arabidopsis thaliana in complex with cystine, and establish the mode of ligand recognition and mechanism for proton-coupled ...
