Hence, this enzyme has one substrate, styrene oxide, and one product, phenylacetaldehyde.

This enzyme belongs to the family of isomerases, specifically a class of other intramolecular oxidoreductases. The systematic name of this enzyme class is styrene-oxide isomerase (epoxide-cleaving). This enzyme is also called SOI. This enzyme participates in styrene degradation, and is the second step of the pathway after the epoxidation of styrene by styrene monooxygenase.
