SU1 — Zea mays

Summary

ZM00001EB237800 (SU1) on maize chromosome 5 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. It is linked to endosperm development and digestion, and localizes to the isoamylase complex, including the chloroplast isoamylase complex. SU1 has been connected to sugar content, protein content, and grain yield.
