ID   1.21.99.5
DE   tetrachloroethene reductive dehalogenase.
AN   tetrachloroethene reductase.
CA   A + chloride + H(+) + trichloroethene = AH2 + tetrachloroethene.
CC   -!- This enzyme allows the common pollutant tetrachloroethene to support
CC       bacterial growth and is responsible for disposal of a number of
CC       chlorinated hydrocarbons by this organism.
CC   -!- The reaction occurs in the reverse direction.
CC   -!- The enzyme also reduces trichloroethene to dichloroethene.
CC   -!- Although the physiological reductant is unknown, the supply of
CC       reductant in some organisms is via reduced menaquinone, itself formed
CC       from molecular hydrogen, via EC 1.12.5.1.
CC   -!- Methylviologen can act as electron donor.
CC   -!- Formerly EC 1.97.1.8.
