General annotation (Comments)

Function

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 By similarity.

Catalytic activity

Transfers a segment of a (1->4)-alpha-D-glucan to a new position in an acceptor, which may be glucose or a (1->4)-alpha-D-glucan.

Subcellular location

Cytoplasm › cytosol Potential.

Sequence similarities

Belongs to the disproportionating enzyme family.

Contains 2 CBM20 (carbohydrate binding type-20) domains.

Sequence caution

The sequence AK067082 differs from that shown. Reason: Frameshift at positions 712 and 768.
