Protein

4-alpha-glucanotransferase, chloroplastic/amyloplastic

Gene
DPEP
Organism
Solanum tuberosum (Potato)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at protein leveli

Functioni

May act during starch breakdown to convert small oligosaccharides into larger molecules upon which starch phosphorylase can act, or may change the structure of starch molecules and grain architecture by modifying chain length, or may generate from starch and glucose oligosaccharides which can serve either as primers for new starch phosphoenzyme.

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.
