>gnl|CDD|29040 cd00134, PBPb, Bacterial periplasmic transport systems use membrane-bound complexes and substrate-bound, membrane-associated, periplasmic binding proteins (PBPs) to transport a wide variety of substrates, such as, amino acids, peptides, sugars, vitamins and inorganic ions. PBPs have two cell-membrane translocation functions: bind substrate, and interact with the membrane bound complex. A diverse group of periplasmic transport receptors for lysine/arginine/ornithine (LAO), glutamine, histidine, sulfate, phosphate, molybdate, and methanol are included in the PBPb CD.. Length = 218
