Reductive dechlorination of ortho-chlorophenols. Dechlorinates in the ortho position with respect to the hydroxyl group. Inhibited by sulfide and to a lesser extent by nitrite. Associated with the cell membrane. Probably binds to peptidoglycans of the cell membrane and cell wall. By 2,4,6-trichlorophenol. LysM domains are thought to be involved in peptidoglycan binding.
