FIG 3 .
Carbon starvation-like state of the plasma membrane ATPase (PMA1) in cellobiose-fermenting cells. (A) Phosphorylation states of Pma1 residues S911 and T912 under carbon starvation, glucose-metabolizing, and cellobiose-metabolizing conditions. (B) Cellobiose consumption efficiency (Ec) of cells expressing Pma1 with phospho-mimic or phosphorylation-preventing mutations at positions serine 911 (S911) and threonine 912 (T912). Phospho-mimic and phosphorylation-preventing mutations at position S911 are presented in green and red, respectively. Phospho-mimic mutations at position T912 are presented in blue. Shown are the means and standard deviations for three biological replicates. The experiments were carried out in two biological replicates, with standard errors of the means shown.
