Xylose and xylose/glucose co-fermentation by recombinant Saccharomyces cerevisiae strains expressing individual hexose transporters

Enzyme and Microbial Technology, 2014
Since the uptake of xylose is believed to be one of the rate-limiting steps for xylose ethanol fermentation by recombinant Saccharomyces cerevisiae strains, we transformed a hxt-null strain lacking the major hexose transporters (hxt1Δ-hxt7Δ and gal2Δ) with an integrative plasmid to overexpress the genes for xylose reductase (XYL1), xylitol ...

Effect of xylose incubation on the glucose transport system in Saccharomyces cerevisiae

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1986
Incubation of Saccharomyces cerevisiae with xylose and ethanol for 16 hours leads to a decrease of hexokinase (and glucokinase) activity in the cells. It does not alter the levels of polyphosphate, orthophosphate and ATP. The transport of the glucose derivative 2-deoxy-D-glucose, a sugar that can be phosphorylated, is inhibited after this treatment ...

d-xylose active transport in the hamster small intestine

Biochimica et Biophysica Acta (BBA) - Biophysics including Photosynthesis, 1966
Abstract D -Xylose is accumulated by rings of hamster small intestine, in vitro, through the same equilibrating mobile-carrier mechanism involved in glucose active transport. It is not necessary to postulate the presence of a distinct accumulation step in order to explain energy-dependent sugar accumulation. The experimental evidence is as follows:

[D-xylose transport in cultured mammalian cells].

Tsitologiia, 1980
The uptake of D-xylose by CHO-K1 cells in monolayer conditions, and by suspended L- and HeLa cells has been studied. The initial velocity is a function of exogenous xylose concentration. The estimated kinetic constants, Km and Vmax, at 37 degrees were, resp., 20 mM and 10 mmol/min for CHO cells, 12.5 mM and 2.8 mmol/min for L-cells, and at 16 degrees ...
