Entry
EC 1.14.14.11               Enzyme                                 

Name
styrene monooxygenase;
StyA;
SMO;
NSMOA
Class
Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen into the other donor
Sysname
styrene,FADH2:oxygen oxidoreductase
Reaction(IUBMB)
styrene + FADH2 + O2 = (S)-2-phenyloxirane + FAD + H2O [RN:R05488]
Reaction(KEGG)
R05488
Substrate
styrene [CPD:C07083];
FADH2 [CPD:C01352];
O2 [CPD:C00007]
Product
(S)-2-phenyloxirane [CPD:C20782];
FAD [CPD:C00016];
H2O [CPD:C00001]
Comment
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.
