D-Glc V_max is expressed as pmol (mg protein)⁻¹ s⁻¹ and the specific cytochalasin B binding, determined using 1 μM cytochalasin B (B₁), is expressed as pmol cytochalasin B (mg protein)⁻¹. Values are the means ± s.e.m. of 3 separate experiments.

^*P < 0.05 compared with HS. There were no significant differences between K_m and K_d values (see Results).
