DSP4

Gene
DSP4
Protein
Phosphoglucan phosphatase DSP4, chloroplastic
Organism
Arabidopsis thaliana
Length
379 amino acids
Function
Starch granule-associated phosphoglucan phosphatase involved in the control of starch accumulation. Acts as major regulator of the initial steps of starch degradation at the granule surface. Functions during the day by dephosphorylating the night-accumulated phospho-oligosaccharides. Can release phosphate from both the C6 and the C3 positions, but dephosphorylates preferentially the C6 position (PubMed:20018599, PubMed:26231210).
