title: Evidence of a glucose proton motive force-dependent permease and a fructose phosphoenolpyruvate:phosphotransferase transport system in Lactobacillus reuteri CRL 1098.
abstract: Sugar uptake and phosphoenolpyruvate phosphorylation assays have shown that the heterofermentative strain Lactobacillus reuteri CRL 1098, of likely probiotic value, can transport D-fructose through an inducible fructose-specific phosphotransferase system (K(m) 95 microM) and D-glucose mainly through a proton motive force-driven permease. These data open new perspectives for metabolic and regulatory studies in this bacterium.
