A mutant of cytochrome P450 from Bacillus megaterium (CYP450BM-3) was prepared by replacing two alanine residues around active site of the enzyme, alanine 328 and alanine 82, with leucine and tryptophan, respectively. The CYP450BM-3 mutant produced 2-octanol selectively from n-octane under atmospheric temperature and pressure; its selectivity was 74%. Furthermore, the mutant produced 1-octanol, which is not produced by wild-type enzyme.
