Background

ADP-glucose pyrophosphorylase (AGPase) catalyses the first committed step in the synthesis of transient starch in chloroplasts and storage starch in amyloplasts in plants (Tetlow et al., 2004). AGPase in higher plants is composed of two distinct subunits encoded by separate genes, forming an L2S2 heterotetramer. The large subunits (L) are modulators of allosteric activity, while the small subunits (S) are the catalytic subunits
