This study has focused on the protein engineering of native and artificial lipocalin variants (Anticalins) to bind novel ligands. By systematically substituting amino acids in the binding pocket of the Anticalin FluA(R95K) its affinity for fluorescein was improved to a dissociation constant of 1 nM. An artificial retinal protein was rationally designed on the basis of human retinol-binding protein. Finally, a novel Anticalin with binding activity for the golden fluorescent protein (GdFP) choromophore was constructed.
