Catalyzes hydrolytic cleavage of carbon-halogen bonds in halogenated aliphatic compounds, leading to the formation of the corresponding primary alcohols, halide ions and protons. 1-haloalkane + H2O = a halide anion + a primary alcohol + H(+) Xenobiotic degradation; haloalkane degradation. Monomer. The recombinant strain obtained by expression of the Tyr-176/Phe-273 mutant in the 2,3-dichloro-1-propanol-utilizing bacterium Agrobacterium radiobacter AD1 is able to utilize the environmental pollutant 1,2,3-trichloropropane (TCP) as the sole carbon and energy source. Belongs to the haloalkane dehalogenase family. Type 2 subfamily.
