Muluken Enyew, Anthony J. Studer, Russell Woodford, Maria Ermakova, Susanne von Caemmerer, Asaph B. Cousins
This study examines the impact of PEPC phosphorylation by PEPC-PK in Zea mays mutants, finding that while phosphorylation affects in vitro enzyme sensitivity to malate, it does not significantly alter photosynthetic performance or growth under field conditions.
