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 Delta-hexachlorocyclohexane degradation Gamma-hexachlorocyclohexane degradation |
Reaction catalyzed by enzyme |
hexachlorocyclohexane <=> 1,3,4,5,6-pentachlorocyclohexene + HCl 1,3,4,5,6-pentachlorocyclohexene <=> 1,3,4,6-tetrachlorocyclohexa-1,4-diene + HCl |
