2-haloacid dehalogenase (configuration-inverting) (EC 3.8.1.10, 2-haloalkanoic acid dehalogenase, 2-haloalkanoid acid halidohydrolase, DL-2-haloacid dehalogenase, DL-2-haloacid dehalogenase (inversion of configuration), DL-2-haloacid halidohydrolase (inversion of configuration), DL-DEXi, (R,S)-2-haloacid dehalogenase (configuration-inverting)) is an enzyme with systematic name (S)-2-haloacid dehalogenase (configuration-inverting).[1][2][3][4][5][6][7][8][9] This enzyme catalyses the following chemical reaction

(1) (S)-2-haloacid + H2O \rightleftharpoons (R)-2-hydroxyacid + halide
(2) (R)-2-haloacid + H2O \rightleftharpoons (S)-2-hydroxyacid + halide

This enzyme dehalogenates both (S)- and (R)-2-haloalkanoic acids.
