Directed enzyme evolution via small and effective neutral drift libraries

Rinkoo D Gupta & Dan S Tawfik

Small libraries for directed evolution can be obtained by neutral drifts that maintain the protein's original function, yielding highly polymorphic, stable and evolvable variants. We describe methods for preparing such libraries, using serum paraoxonase (PON1).
