SU1 — Zea mays

Summary

ZM00001EB086090 (SU1) on maize chromosome 2 encodes an isoamylase 1-3-like C-terminal domain-containing protein with isoamylase activity. This gene is associated with carbohydrate storage, starch metabolism, and specifically amylopectin anabolism and starch breakdown, as well as endosperm development and digestion. The product localizes to the isoamylase complex and the chloroplast isoamylase complex. SU1 has been connected to grain yield, sugar content, and protein content. Related genes in other species link the isoamylase family to EC 3.2.1.68.
