comment
  • FUNCTION Involved in synthesis of starch. Catalyzes the synthesis of ADP-glucose, a molecule that serves as an activated glycosyl donor for alpha-1,4-glucan synthesis. Essential for starch synthesis in leaf chloroplasts and endosperm amyloplasts.CATALYTIC ACTIVITY alpha-D-glucose 1-phosphate + ATP + H(+) = ADP-alpha-D-glucose + diphosphateACTIVITY REGULATION Activated by 3'phosphoglycerate, inhibited by orthophosphate. Allosteric regulation.PATHWAY Glycan biosynthesis; starch biosynthesis.SUBUNIT Heterotetramer composed of two small and two large subunits.SUBCELLULAR LOCATION Expressed in leaves.DEVELOPMENTAL STAGE Expressed in developing seeds from 10 to 20 days after flowering (DAF).INDUCTION Induced by sucrose, glucose and abscisic acid (ABA).SIMILARITY Belongs to the bacterial/plant glucose-1-phosphate adenylyltransferase family.
