FIGURE 2.

Both Hxk2 and Glk1/4 play a role in glucose metabolism, while only Hxk2 has an effect on fructose metabolism. The cells were grown in SC medium with 2% glycerol before proteins were isolated and kinase activity was measured. The values of the deletion strains are normalized relative to the wild type strain which has 100% kinase activity. (A) Kinase activity on glucose. (B) Kinase activity on fructose. The average of three independent experiments is shown, and the error bars represent the standard error of the mean (SEM).
