FIG. 3.
Sugar-specific PTS activity of S. mutans UA159 and EIIFru− strains (TW30, TW31, and TW32) grown in glucose (A) and mannose (B). The glucose-, fructose-, and mannose-specific PTS activities are indicated as GLC, FRU, and MAN, respectively. The values are the means ± SD from at least three individual experiments.
