4-alpha-glucanotransferase DPE2

Gene

DPE2

Organism
Oryza sativa subsp. japonica (Rice)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

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 activityi

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.
