Polyhalogenated dibenzo-p-dioxins are arguably among the most toxic molecules known to man. In addition to anthropogenic sources, marine invertebrates also harbor polybrominated dibenzo-p-dioxins of as yet unknown biogenic origin. Here, we report that the bmp gene locus in marine bacteria, a recently characterized source of polybrominated diphenyl ethers, can also synthesize dibenzo-p-dioxins by employing different phenolic initiator molecules. Our findings also diversify the structural classes of diphenyl ethers accessed by the mmp biosynthetic pathway. This report lays the biochemical foundation of a likely biogenetic origin of dibenzo-p-dioxins present in the marine metabolome and greatly expands the toxicity potential of marine derived polyhaloganated natural products.
