ID 1.14.13.69 DE alkene monooxygenase. AN alkene epoxygenase. CA H(+) + NADH + O2 + propene = 1,2-epoxypropane + H2O + NAD(+). CC -!- The enzyme from Xanthobacter sp. strain Py2 is a multicomponent CC enzyme comprising: CC (1) an NADH reductase, which provides the reductant for O2 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 C2 to C6 aliphatic alkenes. CC -!- With propene as substrate, the stereospecificity of the epoxypropane CC formed is 95% (R) and 5% (S). DR O87082, XAMOA_XANP2; Q9ZET6, XAMOB_XANP2; Q9ZET3, XAMOE_XANP2; //
