  1. PFK activity was measured at pH = 7.4, F6P and ATP range 0.1–8.0 mM. Kinetic parameters for the substrate curves were calculated by non-linear regression using the software Sigma-Plot 10 (Systat, CA, USA). Values are the mean ± SEM. Data from three independent experiments were used to fit through the equations described in the Methods. Vmax - maximal velocity; h – Hill’s coeficient; Kprime – K0.5^h, Ki – constant of inhibition
