Maize leaf phosphoenolpyruvate carboxylase: phosphorylation of Ser15 with a mammalian cyclic AMP-dependent protein kinase diminishes sensitivity to inhibition by malate [PDF]
, 1990 The so-called light-activation of phosphoenolpyruvate carboxylase (PEPC) (EC 4.1.1.31) involved in C4 photosynthesis is known to be mediated by phosphorylation. A cyclic AMP-dependent protein kinase from bovine heart was found to be able to phosphorylate

Marked modulation by phosphate of phosphoenolpyruvate carboxylase in leaves of Amaranthus hypochondriacus, a NAD-ME type C4 plant: decrease in malate sensitivity but no change in the phosphorylation status [PDF]
, 2003 The effect of Pi on the properties of phosphoenolpyruvate carboxylase (PEPC) from Amaranthus hypochondriacus, a NAD-ME type C4 plant, was studied in leaf extracts as well as with purified protein.

Silencing of SbPPCK1-3 Negatively Affects Development, Stress Responses and Productivity in Sorghum
Plants, 2023 Phosphoenolpyruvate carboxylase (PEPC) plays central roles in photosynthesis, respiration, amino acid synthesis, and seed development. PEPC is regulated by different post-translational modifications.

Phosphoenolpyruvate Carboxykinase Is Involved in the Decarboxylation of Aspartate in the Bundle Sheath of Maize [PDF]
, 1999 We recently showed that maize (Zea mays L.) leaves contain appreciable amounts of phosphoenolpyruvate carboxykinase (PEPCK; R.P. Walker, R.M. Acheson, L.I. Técsi, R.C. Leegood [1997] Aust J Plant Physiol 24: 459–468).

Bacterial‐ and plant‐type phosphoenolpyruvate carboxylase polypeptides interact in the hetero‐oligomeric Class‐2 PEPC complex of developing castor oil seeds [PDF]
The Plant Journal, 2007 SummaryTwo classes of phosphoenolpyruvate carboxylase (PEPC) sharing the same 107‐kDa catalytic subunit (p107) were previously purified from developing castor oil seed (COS) endosperm. The association of p107 with an immunologically unrelated 64‐kDa polypeptide (p64) causes pronounced physical and kinetic differences between the Class‐1 PEPC p107 ...

Plants, 2021 Phosphoenolpyruvate carboxylase (PEPC) is a ubiquitous cytosolic enzyme that catalyzes the irreversible β-carboxylation of phosphoenolpyruvate (PEP) in presence of HCO3− to produce oxaloacetate (OAA) during carbon fixation and photosynthesis.

Genomic and Cis‐Regulatory Basis of a Plastic C3‐C4 Photosynthesis in Eleocharis Baldwinii
Advanced Science, EarlyView.The sedge Eleocharis baldwinii remarkably switches between C3‐like and C4‐like photosynthesis in response to environmental conditions. Combining gap‐free genome assembly with single‐cell multi‐omics, this study uncovers how subgenome dominance and cell‐specific cis‐regulation enable C4 photosynthesis.
