a haloacetate + H2O = a halide anion + glycolate + H(+) Two haloacetate dehalogenase enzymes exist in Moraxella strain B. DehH1 acts predominantly on fluoroacetate, dehH2 acts on chloro-, bromo- and iodoacetate, but not on fluoroacetate. Belongs to the HAD-like hydrolase superfamily. S-2-haloalkanoic acid dehalogenase family.
