Abstract: Methods for catalyzing C-H insertion reactions using heme enzymes are described. The present disclosure provides a method for producing a C-H insertion product comprising providing an substrate having an sp 3 -hybridized C-H bond, a carbene precursor such as a diazo reagent, and a heme enzyme, and admixing the components in a reaction for a time sufficient to produce the C-H insertion product. Heme enzyme variants useful for carrying out in vivo and in vitro C-H insertion reactions, as well as expression vectors and host cells expressing the heme enzymes, are also described.

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.

Abstract: Glucose oxidase enzymes are provided, including novel variants of galactose oxidase enzymes. The polynucleotides that encode these novel variants can be expressed in recombinant host cell expression systems. The novel variant oxidase enzymes are capable of oxidizing compounds towards which wild-type galactose oxidase (e.g. D-galactose:oxygen 6-oxidoreductase, GAO; EC 1.1.3.9) has little or no activity. Preferred galactose oxidase variants are those which that have improved capability to oxidize secondary alcohols and/or D-glucose relative to the wild-type enzyme.

Abstract: The invention relates to improved methods for directed evolution of polymers, including directed evolution of nucleic acids and proteins. Specifically, the methods of the invention include analytical methods for identifying "crossover locations" in a polymer. Crossovers at these locations are less likely to disrupt desirable properties of the protein, such as stability or functionality. The invention further provides improved methods for directed evolution wherein the polymer is selectively recombined at the identified "crossover locations". Crossover disruption profiles can be used to identify preferred crossover locations. Structural domains of a biopolymer can also be identified and analyzed, and domains can be organized into schema. Schema disruption profiles can be calculated, for example based on conformational energy or interatomic distances, and these can be used to identify preferred or candidate crossover locations. Computer systems for implementing analytical methods of the invention are also provided.
