Glossary: 2-(1,2-epoxy-1,2-dihydrophenyl)acetyl-CoA = 2-{7-oxabicyclo[4.1.0]hepta-2,4-dien-1-yl}acetyl-CoA
oxepin-CoA = 2-oxepin-2(3H)-ylideneacetyl-CoA
Other name(s): paaG (gene name); 1,2-epoxyphenylacetyl-CoA isomerase (misleading)
Systematic name: 2-(1,2-epoxy-1,2-dihydrophenyl)acetyl-CoA isomerase
Comments: The enzyme catalyses the reversible isomerization of 2-(1,2-epoxy-1,2-dihydrophenyl)acetyl-CoA to the unusual unsaturated, oxygen-containing, seven-member heterocyclic enol ether 2-oxepin-2(3H)-ylideneacetyl-CoA, as part of an aerobic phenylacetate degradation pathway.
