| Research Abstract |
Regio- and enantioelectivities for alcohol isomes from n-alkanes by soluble methane monooxygenase, particulate methane monooxygenase, ammonia monooxygenase, and cytochrome P450 BM-3 were measured for investigating the influence of cavity structure of enzymic active site on n-alkane recognition at the active site. From the selectivity, orientation of n-alkanes at the active site of enzymes was determined. According to the active site structure of the enzymes used here, we revealed that n-alkane recognition was dependent on the volume of active site cavity and the properties of amino acid residues composing the cavity.
