2.4.1.242 | protein targeting to starch PTST |
protein targeting to starch, PTST, is required for localising granule-bound starch synthase to starch granules and for normal amylose synthesis. PTST is a plastidial protein possessing an N-terminal coiled coil domain and a C-terminal carbohydrate binding module. Enzyme GBSS physically interacts with protein PTST via a coiled coil. The CBM48 domain of PTST, which mediates its interaction with starch granules, is also required for correct GBSS localisation |
