additional information | construction of a number of strains lacking portions of the chromosomal dmsABC operon. The mutant strains fail to grow anaerobically on glycerol minimal medium with dimethyl sulfoxide as the sole terminal oxidant but exhibit normal growth with nitrate, fumarate, and trimethylamine N-oxide. In vivo complementation of the mutant with plasmids carrying various dms genes, singly or in combination, reveal that the expression of all three subunits is essential to restore anaerobic growth. Expression of the DmsAB subunits without DmsC results in accumulation of the catalytically active dimer in the cytoplasm. The dimer is thermolabile and catalyzes the reduction of various substrates in the presence of artificial electron donors. Dimethylnaphthoquinol is oxidized only by the holoenzyme. Results suggest that the membrane-intrinsic subunit is necessary for anchoring, stability, and electron transport. The C-terminal region of DmsB appears to interact with the anchor peptide and facilitates the membrane assembly of the catalytic dimer | Escherichia coli |
