Other name(s):

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)

Systematic name:

(S)-2-haloacid dehalogenase (configuration-inverting)

Comments:

Dehalogenates both (S)- and (R)-2-haloalkanoic acids to the corresponding (R)- and (S)-hydroxyalkanoic acids, respectively, with inversion of configuration at C-2. The enzyme from Pseudomonas sp. 113 acts on 2-haloalkanoic acids whose carbon chain lengths are five or less.
