CC   -!- FUNCTION: Component of the alkene monooxygenase multicomponent enzyme
CC       system which catalyzes the O2- and NADH-dependent epoxidation of short
CC       chain (C2 to C6) alkenes to their corresponding epoxides
CC       (PubMed:10103255, PubMed:1444418, PubMed:9312093). Also able to
CC       catalyze the oxidation of a number of chlorinated alkenes, including
CC       trichloroethylene, cis- and trans-1,2-dichloroethylene, vinyl chloride,
CC       1-chloropropylene, 1,3-dichloropropylene and 2,3-dichloropropylene
CC       (PubMed:1444418). {ECO:0000269|PubMed:10103255,
CC       ECO:0000269|PubMed:1444418, ECO:0000269|PubMed:9312093}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H(+) + NADH + O2 + propene = 1,2-epoxypropane + H2O + NAD(+);
CC         Xref=Rhea:RHEA:11792, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,

CC         Evidence={ECO:0000269|PubMed:1444418, ECO:0000269|PubMed:9312093};
CC   -!- ACTIVITY REGULATION: Inhibited by propyne.
CC       {ECO:0000269|PubMed:1444418}.
CC   -!- SUBUNIT: The alkene monooxygenase multicomponent enzyme system is
CC       composed of an electron transfer component and a monooxygenase
CC       component interacting with the effector protein XamoD. The electron
CC       transfer component is composed of a ferredoxin reductase (XamoF) and a
CC       ferredoxin (XamoC), and the monooxygenase component is formed by a
CC       heterohexamer (dimer of heterotrimers) of two alpha subunits (XamoA),
CC       two beta subunits (XamoE) and two gamma subunits (XamoB).
CC       {ECO:0000269|PubMed:9312093}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305|PubMed:9312093}.
CC   -!- INDUCTION: Induced during growth on aliphatic alkenes (such as
CC       propylene, ethylene and 1-butylene), epoxides (such as propylene oxide
CC       and 1,2-epoxybutane) and chlorinated alkenes and epoxides (such as
CC       vinyl chloride, cis- and trans-1,2-dichloroethylene, 1-chloropropylene,
CC       1,3-dichloropropylene, epichlorohydrin, and epifluorohydrin). Repressed
CC       during growth on other carbon sources. {ECO:0000269|PubMed:8572713}.
CC   -!- SIMILARITY: Belongs to the TmoB/XamoB family. {ECO:0000305}.
