Catalyzes hydrolytic cleavage of carbon-halogen bonds in halogenated aliphatic compounds, leading to the formation of the corresponding primary alcohols, halide ions and protons. Has a broad substrate specificity, which includes mono- and di-chlorinated and brominated alkanes. The highest activity was found with 1,2-dibromoethane, whereas low activity was measured with the analog 1,2-dichloroethane. 1-haloalkane + H2O = a halide anion + a primary alcohol + H(+) Xenobiotic degradation; 1,2-dibromoethane degradation. Monomer. Constitutively expressed. Belongs to the haloalkane dehalogenase family. Type 2 subfamily.
