| Abstract: | The genes (dms) encoding the dimethylsulfoxide reductase protein complex have been cloned and sequenced from Haemophilus influenzae (Hi) type b (Hib) strain Eagan. The Hib dms genes are arranged as an operon whose genomic organization is similar to that of the Escherichia coli (Ec) dmsABC operon. The deduced Hib DmsA, DmsB and DmsC amino-acid sequences are highly homologous to their Ec counterparts and nearly identical to the recently published sequences of the Hi type-d strain Rd Dms proteins. Hi dimethylsulfoxide reductase appears to be a new member of the superfamily of oxidoreductase enzymes |
