additional information dehalogenation of tetrachloroethene results in a similar extent of C and Cl isotope fractionation, and in similar dual element isotope slopes for PceA enzyme and for abiotic dehylogenation by corrinoids. Catalytic dehalogenation by enzymes and different corrinoids display mechanistic and/or kinetic differences Sulfurospirillum multivorans ?

Cofactor

Cofactor Comment Organism Structure
vitamin B12 PceA dehalogenase harbors either norpseudo-B12 as cofactor when Sulfurospirillum multivorans has been cultivated in the absence - or nor-B12 when Sulfurospirillum multivorans has been cultivated in its presence of 4,6-dimethylbenzimidazole. Dehalogenation rates with norpseudo-B12 reductive dehalogenase are faster than with nor-B12 Sulfurospirillum multivorans
