Functional analysis of the fructooligosaccharide utilization operon in Lactobacillus paracasei 1195.
The fosABCDXE operon encodes components of a putative fructose/mannose phosphoenolpyruvate-dependent phosphotransferase system and a beta-fructosidase precursor (FosE) that are involved in the fructooligosaccharide (FOS) utilization pathway of Lactobacillus paracasei 1195. The presence of an N-terminal signal peptide sequence and an LPQAG cell wall anchor motif in the C-terminal region of the d...
متن کاملIdentification of a putative operon involved in fructooligosaccharide utilization by Lactobacillus paracasei.
The growth and activity of some Lactobacillus and Bifidobacterium strains are stimulated by the presence of nondigestible fructooligosaccharides (FOS), which are selectively fermented by specific intestinal bacteria. Consumption of FOS, therefore, enriches for those bacteria that possess metabolic pathways necessary for FOS metabolism. In this study, a DNA microarray consisting of 7,680 random ...
متن کاملMetabolism of fructooligosaccharides by Lactobacillus paracasei 1195.
Fermentation of fructooligosaccharides (FOS) and other oligosaccharides has been suggested to be an important property for the selection of bacterial strains used as probiotics. However, little information is available on FOS transport and metabolism by lactic acid bacteria and other probiotic bacteria. The objectives of this research were to identify and characterize the FOS transport system o...
متن کاملFunctional and comparative genomic analyses of an operon involved in fructooligosaccharide utilization by Lactobacillus acidophilus.
Lactobacillus acidophilus is a probiotic organism that displays the ability to use prebiotic compounds such as fructooligosaccharides (FOS), which stimulate the growth of beneficial commensals in the gastrointestinal tract. However, little is known about the mechanisms and genes involved in FOS utilization by Lactobacillus species. Analysis of the L. acidophilus NCFM genome revealed an msm locu...
