    4.1.1.31 | acylation |
acetylation of PEPC at lysine 653 decreases enzymatic activity, leading to reduced glutamate production. NCgl0616, a sirtuin-type deacetylase, deacetylates K653-acetylated PEPC in vitro |

| 4.1.1.31 | more |
modulation of phosphoenolpyruvate carboxylase in vivo by Ca2+, possible involvement of Ca2+ in up-regulation of PEPC-protein kinase |

| 4.1.1.31 | phosphoprotein |
a marked diurnal rhythm can be seen in the PEPC protein levels and phosphorylation status during May (summer month). In contrast, only the phosphorylation status increases during the day in December (winter month) |

| 4.1.1.31 | phosphoprotein |
C4-PEPC is regulated by phosphorylation by a phosphoenolpyruvate carboxylase kinase, n-butanol leads to the partial inhibition of the C4-PEPC phosphorylation |
704892 |
| 4.1.1.31 | phosphoprotein |
class-1 PEPC phosphorylation uniformly results in enzyme activation at physiological pH |
714099 |
| 4.1.1.31 | phosphoprotein |
in plants cultivated hydroponically at low phosphate levels, during the daytime the cluster root PEPC is activated by phosphorylation at its conserved N-terminal seryl residue. Darkness triggers a progressive reduction in PEPC phosphorylation to undetectable levels, and this is correlated with 75-80 % decreases in concentrations of sucrose and trehalose 6-phosphate |
-, 746756 |
| 4.1.1.31 | phosphoprotein |
monoubiquitinated isoform PPC2 is phosphorylated at its conserved N-terminal seryl phosphorylation site, i.e. Ser13 |
748327 |
| 4.1.1.31 | phosphoprotein |
monoubiquitinated isoform PPC3 is phosphorylated at its conserved N-terminal seryl phosphorylation site, i.e. Ser7 |
748327 |
| 4.1.1.31 | phosphoprotein |
PEPC is phosphorylated only during the dark period, especially at midnight |
