Chains	Enzyme Name	Description	Catalytic Residues
A	(S)-2-haloacid dehalogenase M-CSA #36	(S)-2-haloacid dehalogenase catalyses the hydrolytic dehalogenation of L-2-haloacid to the corresponding D-2-hydroxyacid with the inversion of the configuration at the C2 atom. The degradation of halogenated hydrocarbons used in large quantities to make solvents and plastics. The stereospecificity of this enzyme is of interest for its potential use in the biosynthesis of chiral compounds. It is a member of the haloacid dehalogenase superfamily.
