Agglutinin isolectin or wheat germ agglutinin is a plant protein that binds specifically to sugars expressed by human gastrointestinal epithelial and immune cells[1]. Disease Cold agglutinin disease is a disorder affecting patients with autoimmune anemia[2]. Structural highlights Agglutinin binds polysaccharide composed of α- and β-mannose in its active site[3]. . . . . 3D Structures of agglutinin Agglutinin 3D structures
