BE3 — Triticum turgidum subsp. durum
Summary
TRITD2BV1G146930 (symbol BE3, also known as TtBE3 or TtSBEIIA) on durum wheat chromosome 2B encodes a 1,4-alpha-glucan branching enzyme (Q-enzyme) with isoamylase activity, classified under EC 2.4.1.18 and containing a glycosyl hydrolase family 13 catalytic domain. The gene is associated with starch anabolism, amylopectin anabolism, glycogen anabolism, and starch metabolism, as well as starch breakdown and fermentation. It has been linked to amyloplast and chloroplast isoamylase complex localization, and connected to grain weight, grain yield, starch content, and starch digestibility traits. Studies of related genes in other species link the family to starch biosynthesis, amylopectin content, seed weight, grain size, and drought tolerance.
