||Maize plants (Zea mays cv. Dekalb XL81) were grown in soil in a glasshouse between 12 and 30°C leaf tissue was homogenized to extract PDRP. Assay of activation and inactivation of pyruvate,Pi dikinase. All assays were conducted at pH 8.3 unless stated otherwise.
||This value for the reaction: PDRP(with thr and his residues)+ATP+PI=E(with thr residue and phosphorylated His residue) + AMP +PPi
