Relevance Haloalkane dehalogenase is tested for the biodegredation of toxic industrial by-products. Fluoroacetate dehalogenase is tested for the biodegredation of the poisonous fluroacetate which can kill livestock and is found in some plants in Australia, Africa and Central America. Structural highlights In the fluoroacetate dehalogenase complex with halide, the iodide is seen in the active site cavity between two tryptophans (in cyan). 3D structures of dehalogenase Dehalogenase 3D structures
