Addition of L-[U-14C]glutamate to a suspension of mechanically isolated asparagus (Asparagus sprengeri Regel) mesophyll cells results in (a) alkalinization of the medium, (b) uptake of L-[U-14C] ...
Electrogenic sugar symport is driven by Δ H+, Na+ or Li+, depending on the coupling cation 4. Thermodynamically, MelB transduces the free energy from the downhill translocation of a cation to drive ...
The electrogenicity, pH-dependence, and stoichiometry of the proton-sucrose symport were examined in plasma membrane vesicles isolated from sugar beet (Beta vulgaris L. cv Great Western) leaves.
