DE   Alkene monooxygenase.
AN   Alkene epoxygenase.
CA   Propene + NADH + O(2) = 1,2-epoxypropane + NAD(+) + H(2)O.
CF   Iron.
CC   -!- The enzyme from Xanthobacter sp. strain Py2 is a multicomponent
CC       enzyme comprising:
CC       (1) an NADH reductase, which provides the reductant for O(2)
CC       activation.
CC       (2) a Rieske-type ferredoxin, which is an electron-transfer protein.
CC       (3) an oxygenase, which contains the catalytic center for alkene
CC       epoxidation.
CC       (4) a small protein of unknown function that is essential for
CC       activity.
CC   -!- The enzyme oxygenates C(2) to C(6) aliphatic alkenes.
CC   -!- With 1,2-epoxypropane as substrate, the stereospecificity of the
CC       epoxypropane formed is 95% (R) and 5% (S).
