Phosphotransferase.

4-alpha-glucanotransferase DPE1, chloroplastic/amyloplastic; Chloroplastic alpha-glucanotransferase involved in maltotriose metabolism. Probably uses maltotriose as substrate to transfer a maltosyl unit from one molecule to another, resulting in glucose and maltopentaose. The latter can then be further metabolized to maltose and maltotriose by beta-amylase. Required for normal starch degradation in leaves; Belongs to the disproportionating enzyme family.

Phosphotransferase.

4-alpha-glucanotransferase DPE2; Cytosolic alpha-glucanotransferase essential for the cytosolic metabolism of maltose, an intermediate on the pathway by which starch is converted to sucrose in leaves at night. Metabolizes maltose exported from the chloroplast and is specific for beta-maltose. May play a role in freezing tolerance. Temperature drop induces inactivation of DPE2 that leads to rapid accumulation of maltose, a solute that protects cells from freezing damage. Belongs to the disproportionating enzyme family.
