The complex regulatory properties of the plastidial phosphorylase L80 intrinsically disordered region
Plastidial α-glucan phosphorylase (Pho1) regulates starch metabolism and also modulates photosystem I (PSI) activity. In rice, Pho1 contains an 80-amino-acid intrinsically disordered region (IDR), L80, that acts as a negative regulator. While total removal of the L80 IDR boosts seedling growth, flowering time, overall...
