Molecular cloning and functional analysis of a sugar transporter gene (CsTST2) from cucumber (Cucumis sativus L.)

Biotechnology & Biotechnological Equipment, 2019
Tonoplast sugar transporters (TSTs) usually act as antiporters to import sugars across the tonoplast and play essential roles in regulating diverse growth and developmental processes as well as in response to various abiotic stresses in plants.

Transforming growth factor β signaling upregulates the expression of human GDP-fucose transporter by activating transcription factor Sp1. [PDF]

PLoS ONE, 2013
GDP-fucose transporter plays a crucial role in fucosylation of glycoproteins by providing activated fucose donor, GDP-fucose, for fucosyltransferases in the lumen of the Golgi apparatus. Fucose-containing glycans are involved in many biological processes,

Sucrose- and H+-dependent charge movements associated with the gating of sucrose transporter ZmSUT1 [PDF]

, 2010
Background: In contrast to man the majority of higher plants use sucrose as mobile carbohydrate. Accordingly proton-driven sucrose transporters are crucial for cell-to-cell and long-distance distribution within the plant body.

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Conformational transitions of the sodium-dependent sugar transporter, vSGLT [PDF]

, 2018
Significance Transporters isomerize between conformations to shuttle cargo across membranes, but the mechanism is not understood. Double electron–electron resonance measurements on the sodium-dependent sugar transporter (vSGLT) were used to ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Short-Term Adaptation Modulates Anaerobic Metabolic Flux to Succinate by Activating ExuT, a Novel D-Glucose Transporter in Escherichia coli

Frontiers in Microbiology, 2020
The sugar phosphotransferase system (PTS) is an essential energy-saving mechanism, particularly under anaerobic conditions. Since the PTS consumes equimolar phosphoenolpyruvate to phosphorylate each molecule of internalized glucose in the process of ...

Time-resolved measurements of sugar-binding-induced conformational changes in the melibiose permease from Escherichia coli [PDF]

, 2008
The melibiose permease (MelB) of E.coli functions as a secondary-active symporter by using the electrochemical H+, Na+, or Li+ gradient to accumulate, e.g., melibiose [review in Pourcher et al. 1990a].

The sweet life: diet sugar concentration influences paracellular glucose absorption [PDF]

, 2008
Small birds and bats face strong selection pressure to digest food rapidly in order to reduce digesta mass carried during flight. One mechanism is rapid absorption of a high proportion of glucose via the paracellular pathway (transfer between epithelial ...
