Figure 6.

Dose responses of AtPGDH 3-PGA-oxidation activities to effector amino acids. Specific activities of AtPGDHs at various concentrations of effectors were measured and are expressed relative to those in the absence of effectors. Data are presented as means and standard errors of six technical replicates (n = 6). Regression curves of Hill equations are shown with determination coefficients (R²). Half maximal effective concentrations (EC₅₀) and Hill coefficients of effector amino acids are summarized in the table.
