Figure 2. PFK-L is as active as PFK-M with respect to ATP, but much less active with respect to F6P.

Panel A shows similar kinetic properties with respect to ATP titrations (F6P 4 mM) for PFK-M (blue squares with solid lines) and PFK-L (red circles with dotted lines) with PFK-P (green triangles with dot-dash lines) showing lower activity. Panel B shows PFK-M to be much more active than PFK-L or PFK-P with respect to F6P titrations (ATP 0.5 mM). (n = 6).
