5.3.99.7 metabolism the enzyme is involved in the styrene degradation pathway, overview -, 728003 5.3.99.7 metabolism the enzyme is part of the upper pathway of styrene degradation via side chain oxygenation -, 726724 5.3.99.7 additional information in strain ST-10, which lacks a styrene oxide isomerase, styrene oxide is converted to phenylacetaldehyde by spontaneous chemical reaction. The strain accumulates styrene oxide as a metabolic intermediate. The produced phenylacetaldehyde is converted to phenylacetic acid in strain ST-10 as well as in strain ST-5 -, 728003
