Take me to UniProt BETA
UniProtKB - F4J117 (LSF1_ARATH)
Protein
Phosphoglucan phosphatase LSF1, chloroplastic
Gene
LSF1
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Functioni
Starch granule-associated phosphoglucan phosphatase involved in the control of starch accumulation. Participates in the regulation of the initial steps of starch degradation at the granule surface. May release a different set of phosphate groups from those removed by DSP4.
