A halohydrin dehalogenase is an enzyme involved in the bacterial degradation of vicinal halohydrins. In several species of bacteria, it catalyses the dehalogenation of halohydrins to produce the corresponding epoxides. Different isoforms of the enzyme fall into one of three groups, A, B or C. Halogenases of the same class are genetically similar, but differ greatly from halogenases from a different group. Currently the most well-studied isoform is HheC which is purified from the bacterial species Agrobacterium radiobacter. The ability to dehalogenate organic compounds as well as form enantiomeric selective epoxides have generated interest in the potential of this enzyme in the biochemical field.

Adsorbable organic halides (AOX) is a measure of the organic halogen load at a sampling site such as soil from a land fill, water, or sewage waste. The procedure measures chlorine, bromine, and iodine as equivalent halogens, but does not measure fluorine levels in the sample.
Reductive dehaholagenses (EC 1.97.1.8) are a group of enzymes utilized in organohalide respiring bacteria. These enzymes are mostly attached to the periplasmic side of the cytoplasmic membrane and play a central role in energy-conserving respiratory process for organohalide respiring bacteria by reducing organohalides. During such reductive dehalogenation reaction, organohalides are used as terminal electron acceptors. They catalyze the following general reactions:
