Protein: Protein LIKE EARLY STARVATION, chloroplastic (Q5EAH9)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Binds preferentially to highly ordered alpha-glucans, such as starch and crystalline maltodextrins. Involved in the organization of the starch granule matrix, thus influencing starch turnover by modulating the accessibility of starch polymers to modifying and degrading enzymes involved in phosphorylation, hydrolyzes and synthesis, including starch synthases (SSI and SSIII), starch phosphorylases (PHS1), isoamylase, beta-amylase, glucan water dikinase (GWD) and phosphoglucan water dikinase (PWD).
Subcellular location: Plastid, chloroplast stroma {ECO:0000269|PubMed:17631522, ECO:0000269|PubMed:27207856}. Note=Binds to starch granules in chloroplasts. {ECO:0000269|PubMed:17631522, ECO:0000269|PubMed:27207856}.
