Reaction: styrene + FADH2 + O2 = (S)-2-phenyloxirane + FAD + H2O
Other name(s): StyA; SMO; NSMOA
Systematic name: styrene,FADH2:oxygen oxidoreductase
Comments: The enzyme catalyses the first step in the aerobic styrene degradation pathway. It forms a two-component system with a reductase (StyB) that utilizes NADH to reduce flavin-adenine dinucleotide, which is then transferred to the oxygenase.
