Abstract excerpt
We report a method for in vitro selection of catalytically active enzymes from large libraries of variants displayed on the surface of the yeast S. cerevisiae. Two libraries, each containing approximately 2 x 10(6) variants of horseradish peroxidase (HRP), were constructed; one involved error-prone PCR that sampled mutations throughout the coding sequence, whereas the other involved complete combinatorial...
