Alkene monooxygenase explained

alkene monooxygenase
Ec Number:	1.14.13.69
Go Code:	0018645

In enzymology, an alkene monooxygenase is an enzyme that catalyzes the chemical reaction

propene + NADH + H⁺ + O₂

\rightleftharpoons 1,2-epoxypropane + NAD⁺ + H₂O

The 4 substrates of this enzyme are propene, NADH, H⁺, and O₂, whereas its 3 products are 1,2-epoxypropane, NAD⁺, and H₂O.

This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with NADH or NADPH as one donor, and incorporation of one atom o oxygen into the other donor. The systematic name of this enzyme class is alkene,NADH:oxygen oxidoreductase. This enzyme is also called alkene epoxygenase. This enzyme participates in tetrachloroethene degradation.
