Abstract: The present disclosure teaches that the recombination of homologous sequences of P450 enzymes, with the aid of SCHEMA to predict a resulting protein structure, is able to generate libraries of chimeras with significant functional diversity. Additionally, the members of these libraries demonstrate superior or unexpected new properties, which correlate with other factors that are observable in the library. Thus, the making of libraries of optimized P450 enzymes, the analysis of libraries to identify an optimized subset, and the optimized chimeras with improved or altered functionalities are all taught in the present disclosure.
