Enzyme name Gamma-hexachlorocyclohexane dehydrochlorinase
Description Catalyzes the conversion of the important environmental pollutant gamma-hexachlorocyclohexane (gamma-HCH or lindane) to 1,3,4,6-tetrachloro-1,4-cyclohexadiene (1,4-TCDN) via gamma-pentachlorocyclohexene (gamma-PCCH), proceeding by two successive 1,2-anti conformationally dependent dehydrochlorinations
Synonyms LinA
dehydrochlorinase
gamma-BHC dehydrochlorinase
gamma-hexachlorocyclohexane dehydrochlorinase
HCH dehydrochlorinase
Lina2
gamma-HCH dehydrochlorinase
Degradation pathway Alpha-hexachlorocyclohexane degradation
Beta-hexachlorocyclohexane degradation
