Abstract excerpt
Pyruvate orthophosphate dikinase (PPDK, E.C. 2.7.9.1) is an abundant enzyme in the leaves of C4 plants associated with the dicarboxylic acid pathways of CO2 fixation in the dark. PPDK activity has also been detected in the seeds of maize and other, non-C4 cereals, where its role has yet to be established. Using an anti-PPDK serum, two cross-reacting species of M(r) close to 90 000 were detected in developing...
