Nucleotide sequence of the genes, encoding the pentaheme cytochrome (dmsC) and the transmembrane protein (dmsB), involved in dimethyl sulfoxide respiration from Rhodobacter sphaeroides f. sp. denitrif
文摘
The nucleotide sequence of the genes encoding a pentaheme cytochrome (dmsC) and a transmembrane protein (dmsB) were determined upstream of the dmsA gene encoding dimethyl sulfoxide reductase from Rhodobacter sphaeroides f. sp.denitrificans. dmsC and dmsB encode proteins of 404 and 226 amino acid residues, which show 40 % and 26 % identity to the pentaheme cytochrome TorC and the transmembrane protein TorD, respectively, of the trimethylamine N-oxide reduction system in Escherichia coli.
