[[http://www.uniprot.org/uniprot/LINB_SPHPI LINB_SPHPI]] 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 since not only monochloroalkanes (C3 to C10) but also dichloroalkanes (> C3), bromoalkanes, and chlorinated aliphatic alcohols were good substrates. Shows almost no activity with 1,2-dichloroethane, but very high activity with the brominated analog. Is involved in the degradation of the important environmental pollutant gamma-hexachlorocyclohexane (lindane) as it also catalyzes conversion of 1,3,4,6-tetrachloro-1,4-cyclohexadiene (1,4-TCDN) to 2,5-dichloro-2,5-cyclohexadiene-1,4-diol (2,5-DDOL) via the intermediate 2,4,5-trichloro-2,5-cyclohexadiene-1-ol (2,4,5-DNOL). | [[http://www.uniprot.org/uniprot/LINB_SPHPI LINB_SPHPI]] Catalyzes hydrolytic cleavage of carbon-halogen bonds in halogenated aliphatic compounds, leading to the formation of the corresponding primary alcohols, halide ions and protons.
