CC -!- FUNCTION: Catalyzes hydrolytic cleavage of carbon-halogen bonds in
CC halogenated aliphatic compounds, leading to the formation of the
CC corresponding primary alcohols, halide ions and protons. Has a broad
CC substrate specificity, which includes terminally mono- and
CC di- chlorinated and brominated alkanes (up to C4 only). The highest
CC activity was found with 1,2-dichloroethane, 1,3-dichloropropane, and
CC 1,2-dibromoethane.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=1-haloalkane + H2O = a halide anion + a primary alcohol +
CC H(+); Xref=Rhea:RHEA:19081, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:15734, ChEBI:CHEBI:16042, ChEBI:CHEBI:18060; EC=3.8.1.5;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=1,2-dichloroethane + H2O = 2-chloroethanol + chloride + H(+);
CC Xref=Rhea:RHEA:25185, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:17996, ChEBI:CHEBI:27789, ChEBI:CHEBI:28200; EC=3.8.1.5;
CC -!- ACTIVITY REGULATION: Inhibited by thiol reagents such as p-
CC chloromercuribenzoate and iodoacetamide.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC pH dependence:
CC Optimum pH is 8.2.;
CC Temperature dependence:
CC Optimum temperature is 37 degrees Celsius.;
CC -!- PATHWAY: Xenobiotic degradation; 1,2-dichloroethane degradation;
CC glycolate from 1,2-dichloroethane: step 1/4.
CC -!- SUBUNIT: Monomer.
CC -!- SIMILARITY: Belongs to the haloalkane dehalogenase family. Type 1
CC subfamily. {ECO:0000305}.
