Evidence of a glucose proton motive force-dependent permease and a fructose phosphoenolpyruvate : phosphotransferase transport system in Lactobacillus reuteri CRL 1098

Sugar uptake and phosphoenolpyruvate phosphorylation assays have shown that the heterofermentative strain Lactobacillus reuteri CRL 1098, of likely pr obiotic value, can transport D-fructose through an inducible fructose-speci fic phosphotransferase system (K-m 95 mu M) and D-glucose mainly through a proton motive force-driven permease. These data open new perspectives for m etabolic and regulatory studies in this bacterium. (C) 1999 Federation of E uropean Microbiological Societies. Published by Elsevier Science B.V.
