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 AB hydrolase superfamily. Epoxide hydrolase family.
