Functions
  • (S)-2-haloacid dehalogenase activity
General Function(s)-2-haloacid dehalogenase activity
Specific FunctionCatalyzes the hydrolytic dehalogenation of small (S)-2-haloalkanoic acids to yield the corresponding (R)-2-hydroxyalkanoic acids. Acts on acids of short chain lengths, C(2) to C(4), with inversion of configuration at C-2.
