In enzymology, a (S)-2-haloacid dehalogenase (EC 3.8.1.2) is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are (S)-2-haloacid and H2O, whereas its two products are (R)-2-hydroxyacid and halide.
This enzyme belongs to the family of hydrolases, specifically those acting on halide bonds in carbon-halide compounds.
The systematic name of this enzyme class is (S)-2-haloacid halidohydrolase.
Other names in common use include 2-haloacid dehalogenase[ambiguous], 2-haloacid halidohydrolase [ambiguous][ambiguous], 2-haloalkanoic acid dehalogenase, 2-haloalkanoid acid halidohydrolase, 2-halocarboxylic acid dehalogenase II, DL-2-haloacid dehalogenase[ambiguous], L-2-haloacid dehalogenase, and L-DEX.
As of late 2007, 10 structures have been solved for this class of enzymes, with PDB accession codes 1AQ6, 1JUD, 1QH9, 1QQ5, 1QQ6, 1QQ7, 1ZRM, 1ZRN, 2NO4, and 2NO5.
