A) DXP synthase. The concentration of pyruvate was varied with increasing concentrations of BAP: 0 (○), 10 (●), 25 (□), and 50 (■) μM BAP. B) E1 subunit of pyruvate dehydrogenase. The concentration of pyruvate was varied at with increasing concentrations of BAP: 0 (○), 0.2 (●), 0.5 (□), and 1.0 (■) mM BAP.
