BE3 — Triticum turgidum subsp. durum
Summary
TRITD2AV1G178500 (symbol BE3, also known as TtSBEIIA) on durum wheat chromosome 2A encodes a glycosyl hydrolase family 13 catalytic domain-containing protein with 1,4-alpha-glucan branching enzyme activity (EC 2.4.1.18) and isoamylase activity. The protein localises to the amyloplast, chloroplast stroma and cytoplasm. This gene is associated with starch metabolism, amylopectin anabolism, glycogen anabolism, starch breakdown, fermentation, and carbohydrate metabolism. It is linked to grain weight, grain yield, starch content and starch digestibility. Related genes in other species are associated with starch biosynthesis in the endosperm. Associations also include embryo development ending in seed dormancy, and the gene is linked to amylopectin structure and reduced maltose accumulation.
