The first step is construction of a mutant library, usually accomplished by random point mutagenesis with error-prone PCR (.) or by DNA shuffling (recombination) (.,.). The second, and most critical step is finding the desired mutants by screening or selection of the libraries. Screens for enzy

As with any high throughput screening approach, a suitable colorimetric or fluorimetric assay must exist (or be developed) for the enzyme function in question.
