Nucleic acids encoding cytochrome P450 variants are provided. The cytochrome P450 variants of have a higher alkane-oxidation capability, alkene-oxidation capability, and/or a higher organic-solvent resistance than the corresponding wild-type or parent cytochrome P450 enzyme. A preferred wild-type cytochrome P450 is cytochrome P450 BM-3. Preferred cytochrome P450 variants include those having an improved capability to hydroxylate alkanes and epoxidate alkenes comprising less than 8 carbons, and have amino acid substitutions corresponding to V78A, H236Q, and E252G of cytochrome P450 BM-3. Preferred cytochrome P450 variants also include those having an improved hydroxylation activity in solutions comprising co-solvents such as DMSO and THF, and have amino acid substitutions corresponding to T235A, R471A, E494K, and S1024E of cytochrome P450 BM-3.

An isolated polypeptide having activity of a cytochrome P450 variant, wherein the variant is characterized as comprising a higher capability than the corresponding wild-type cytochrome P450 to oxidize at least one substrate selected from an alkane comprising a carbon-chain of no more than 8 carbons and an alkene comprising a carbon-chain no more than 8 carbons, and wherein the wild-type cytochrome P450 comprises an amino acid sequence having at least 90% sequence identity to SEQ ID NO:
