Abstract excerpt

Starch is the major carbohydrate reserve in plants, and is degraded for growth at night. Starch breakdown requires reversible glucan phosphorylation at the granule surface by novel dikinases and phosphatases. The dual-specificity phosphatase starch excess 4 (SEX4) is required for glucan desphosphorylation; however, regulation of the enzymatic activity of SEX4 is not well understood. We show that SEX4 switches...
