Jochen Zimmer’s lab published structure of plant cellulose synthase in Science. Cellulose is the most abundant biopolymer produced on earth. Cellulose synthase is an trimeric integral membrane protein that stiches together glucose subunits to form long cellulose cables that constitute the walls of every plant. The structure was revealed by cryo electron microscopy using UVA’s Titan Krios microscope and it explains how this enzyme forms cellulose protofibrils in a biosynthetic pathway that is coupled membrane translocation.
