A NADH turnover rate of 741 min −1 in the oxidition of ethane to ethanol is observed with an engineered form of the heme monooxygenase cytochrome P450 cam —the first example of such activity for a P450 enzyme (GC analysis shown). Ethanol is formed at 78 min −1 (10.5 % coupling). The mutant is ≈45 % high‐spin in the absence of substrate, making it a useful platform for P450 structure–function studies.
