Biochemical Activity (Dephosphorylation)
An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.

The pyruvate,orthophosphate dikinase regulatory proteins of Arabidopsis are both bifunctional and interact with the catalytic and nucleotide binding domains of pyruvate,orthophosphate dikinase.
Pyruvate,orthophosphate dikinase (PPDK) is a key enzyme in C(4) photosynthesis and is also found in C(3) plants. It is post-translationally modified by the PPDK regulatory protein (RP) that possesses both kinase and phosphotransferase activities. Phosphorylation and dephosphorylation of PPDK lead to inactivation and activation respectively. Arabidopsis thaliana contains two genes encoding chloroplastic (RP1) and cytosolic (RP2) isoforms of RP, and ... [more]
