TL;DR: Results are accumulating suggesting that a protein called IIABMan, as well as the phosphocarrier protein HPr, are key regulatory components that allow these bacteria to select rapidly metabolizable sugars, such as glucose or fructose, over less readily utilizable carbohydrates.

TL;DR: It was concluded that xylitol was transported and phosphorylated by a constitutive phosphoenolpyruvate:fructose phosphotransferase system in S. mutans, and the data suggested thatxylitol toxicity in the growth of Streptococcus mutans is caused by the intracellular accumulation of Xylitol phosphate.

TL;DR: The Lactobacillus casei ptsH and ptsI genes, which encode enzyme I and HPr, respectively, the general components of the phosphoenolpyruvate–carbohydrate phosphotransferase system (PTS), are cloned and sequenced and Northern blot analysis revealed that these two genes are organized in a single‐transcriptional unit whose expression is partially induced.

TL;DR: The results clearly indicated that the gal-lac gene cluster was efficiently transcribed in both species, whereas the ribosome binding site of S. thermophilus galK differed from that ofS.

TL;DR: It is possible to increase the production of EPS by ropy S. thermophilus strains through genetic engineering of galactose metabolism, but when used in combination with Lb.
