Description This gene encodes for the large subunit of enzyme ADP-glucose pyrophosphorylase (AGP). The enzyme regulates starch biosynthesis and catalyzes the reaction ATP + alpha-D-glucose 1-phosphate = diphosphate + ADP-glucose. The mutant (Tos17 insertion) line showed that the subunit is required for AGPase activity in leaf tissues and reduces the starch content in the leaf sheath only. The APL1 peptide is localized to the leaf chloroplast. It forms spatiotemporal heterotetramer ADP-glucose pyrophosphorylase enzyme complex together with small subunits. The APL1 dimer interacts with APS2a form of the APS2 (GR:0101319) dimers to form the heterotetramer enzyme complex in leaf chloroplast.
