Large mutant lipocalin libraries were prepared in order to select artificial proteins with biocatalytic properties. The random libraries were then used in carefully designed in vivo selection experiments based on the growth recovery of auxotrophic
Escherichia coli strains.
Furthermore, an Anticalin with specificity for digoxigenin was biophysically characterized. It was also applied in fusion proteins with β-lactamases and an improved alkaline phosphatase. The bifunctional proteins proved to be valuable tools for diagnostic purposes.
