Target Background
Function
Pyruvate orthophosphate dikinase (PPDK) catalyzes the formation of phosphoenolpyruvate. This enzyme plays a crucial role in regulating carbon flux into starch and fatty acids within seeds, as well as in the remobilization of nitrogen reserves during leaf senescence.
Gene References Into Functions
- Arabidopsis utilizes two gluconeogenic pathways for organic acids to support seedling establishment. One pathway involves PCK1, while the other utilizes PPDK. PMID: 25858700
- Overexpression of PPDK during senescence enhances nitrogen remobilization from senescing leaves, leading to increased seed size and seed nitrogen content. PMID: 20202167
- In cotyledons, pyruvate orthophosphate dikinase may be essential for supplying phosphoenol pyruvate to gluconeogenesis. In aging leaves, it facilitates the remobilization of nitrogen to support reproductive tissue development. PMID: 16915520
