>cd01536 PBP1_ABC_sugar_binding_like Periplasmic sugar-binding domain of active transport systems that are members of the type I periplasmic binding protein (PBP1) superfamily. Periplasmic sugar-binding domain of active transport systems that are members of the type I periplasmic binding protein (PBP1) superfamily. The members of this family function as the primary receptors for chemotaxis and transport of many sugar based solutes in bacteria and archaea. The sugar binding domain is also homologous to the ligand-binding domain of eukaryotic receptors such as glutamate receptor (GluR) and DNA-binding transcriptional repressors such as LacI and GalR. Moreover, this periplasmic binding domain, also known as Venus flytrap domain, undergoes transition from an open to a closed conformational state upon the binding of ligands such as lactose, ribose, fructose, xylose, arabinose, galactose/glucose, and other sugars. This family also includes the periplasmic binding domain of autoinducer-2 (AI-2
