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.
CC       {ECO:0000255|HAMAP-Rule:MF_01231}.
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,
