A dehalogenase is a type of enzyme that catalyzes the removal of a halogen atom from a substrate. Examples include: Reductive dehalogenases 4-chlorobenzoate dehalogenase 4-chlorobenzoyl-CoA dehalogenase Dichloromethane dehalogenase Fluoroacetate dehydrogenase Haloacetate dehalogenase (R)-2-haloacid dehalogenase (S)-2-haloacid dehalogenase Haloalkane dehalogenase Halohydrin dehalogenase Haloacetate dehalogenase Tetrachloroethene reductive dehalogenase References
