Domain & Motif Annotations
Domain (CC)
Transport is mediated via a series of conformation changes, switching between a conformation where the substrate-binding cavity is accessible from the outside, and a another conformation where it is accessible from the cytoplasm.
Region
277..279; Important for selectivity against fructose
