This family is structurally different from the alpha/beta hydrolase family (Pfam:PF00561). This family includes L-2-haloacid dehalogenase, epoxide hydrolases and phosphatases. The structure of the family consists of two domains. One is an inserted four helix bundle, which is the least well conserved region of the alignment, between residues 16 and 96 of Swiss:P24069. The rest of the fold is composed of the core alpha/beta domain [1]. Those members with the characteristic DxD triad at the N-terminus are probably phosphatidylglycerolphosphate (PGP) phosphatases involved in cardiolipin biosynthesis in the mitochondria [2].	Domain

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.
