摘要
The activity, selectivity and coupling efficiency of alkane oxidation by the monooxygenase enzyme cytochrome P450(cam) can be enhanced by engineering the active site topology to accommodate different alkanes: reducing the active site volume by the Y96F-V247L double mutations resulted in four-fold higher activity for the oxidation of hexane (1) than 3-methylpentane (2) while the larger active site of the Y96A-V247A double mutant gave rise to a two-fold preference for 2 over 1.
