Periplasmic Binding Proteins: A Versatile Superfamily for Protein Engineering

Mary A Dwyer et al. Curr Opin Struct Biol.

Abstract

The diversity of biological function, ligand binding, conformational changes and structural adaptability of the periplasmic binding protein superfamily have been exploited to engineer biosensors, allosteric control elements, biologically active receptors and enzymes using a combination of techniques, including computational design. Extensively redesigned periplasmic binding proteins have been re-introduced into bacteria to function in synthetic signal transduction pathways that respond to extracellular ligands and as biologically active enzymes.
