CC   -!- FUNCTION: Catalyzes the hydrolytic dehalogenation of small (S)-2-
CC       haloalkanoic acids to yield the corresponding (R)-2-hydroxyalkanoic
CC       acids (By similarity). Acts on acids of short chain lengths, C(2) to
CC       C(4), with inversion of configuration at C-2 (By similarity). Active
CC       with 2-halogenated carboxylic acids and converts only the S-isomer (or
CC       L-isomer) of 2-chloropropionic acid with inversion of configuration to
CC       produce R-lactate (or D-isomer) (By similarity).
CC       {ECO:0000250|UniProtKB:Q52087}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=an (S)-2-haloacid + H2O = a (2R)-2-hydroxycarboxylate + a
CC         halide anion + H(+); Xref=Rhea:RHEA:11192, ChEBI:CHEBI:15377,

CC   -!- CATALYTIC ACTIVITY:

CC         Evidence={ECO:0000250|UniProtKB:Q53464};
CC   -!- BIOTECHNOLOGY: (S)-2-haloacid dehalogenases may be used for the
CC       biodegradation of halogenated substances and their derivatives which
CC       are widely used as pesticides, herbicides and other industrial
CC       products. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the HAD-like hydrolase superfamily. S-2-
CC       haloalkanoic acid dehalogenase family. {ECO:0000305}.
