  • Publication number: 20080166747
    Abstract: Biosensors are made by attaching covalently or non-covalently at least one reporter group to one or more specific positions of a bacterial periplasmic binding protein (bPBP). Upon binding of ligand to the biosensor, there is a change in the signal transduced by the reporter group.

  • Patent number: 6977180
    Abstract: The present invention relates, in general, to biosensors and, in particular, to bioelectronic sensors comprising a macromolecule immobilized on an electrode surface so that a redox cofactor that is site-specifically attached to the surface of the macromolecule is between the macromolecule and electrode surface ligand-mediated conformational changes alter the geometry of interaction between the redox cofactor and the electrode surface resulting in a change in electronic coupling between the cofactor and electrode.

  • Publication number: 20040229290
    Abstract: We describe processes for the protein structure-based design or redesign of receptor-ligand interfaces (ligand-binding sites) in which a ligand is recognized and bound. Receptors designed in this manner can then be synthesized artificially or naturally, or used to engineer cells, tissues, or organisms. They can be further evaluated by empirical methods (e.g., ligand recognition and binding, signaling, catalysis), subjected to further improvement, and/or the process can be iterated in multiple cycles (e.g., consideration of quantitative structure-activity relationship data).
