Phenotypic characterisation and genetic complementation of dimethylsulfoxide respiratory mutants of Rhodobacter sphaeroides and Rhodobacter capsulatus.

Abstract excerpt

Two chlorate resistant mutants of Rhodobacter sphaeroides were isolated which were deficient in dimethylsulfoxide reductase activity. Immunoblotting experiments showed that the phenotype of these mutants and that of Rhodobacter capsulatus strain DK9, a mutant unable to reduce dimethylsulfoxide, was correlated with low or undetectable levels of the dimethylsulfoxide reductase apoprotein. All three mutants were...
