| Primary Identifier | IPR026565 | Type | Family |
| Short Name | PPDK_reg |
| description | This is a family of proteins which are putative bifunctional serine/threonine kinase/phosphorylases involved in the regulation of the pyruvate, phosphate dikinase (PPDK) by catalysing its phosphorylation/dephosphorylation [, ]. In plants, the pyruvate, phosphate dikinase regulatory protein 1 (RP1) is a bifunctional serine/threonine kinase and phosphorylase involved in the dark/light-mediated regulation of PPDK by catalysing its phosphorylation/dephosphorylation. In the dark, RP1 phosphorylates the catalytic intermediate of PPDK (PPDK-HisP), inactivating it. Light exposure induces the phosphorolysis reaction that reactivates PPDK [, , , ]. |
