transformation in synthesis. Recently, a new P450-based enzyme (aMOx) has been evolved
in the laboratory to directly oxidize styrenes to their corresponding aldehydes with high
activity and selectivity. The enzyme utilizes a heme-based, high-valent iron-oxo species as a
catalytic oxidant that normally epoxidizes alkenes, similar to other catalysts. How the
evolved aMOx enzyme suppresses the commonly preferred epoxidation and catalyzes direct …
