On the Road to Bioremediation of “Dioxin”

Mohammadi and Sylvestre [] report engineering of a dioxygenase to create an enzyme that attacks dibenzofuran in the lateral position. Subsequent oxidation and a second dioxygenation produced ring-open products. All metabolites were unambiguously identified by 1H-NMR. This new pathway targets degradation of chlorinated dibenzofurans.
