Protein

Putative dimethyl sulfoxide reductase iron-sulfur subunit B

Gene

dmsB

Organism
Halobacterium salinarum (strain ATCC 700922 / JCM 11081 / NRC-1) (Halobacterium halobium)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript leveli

Functioni

Dimethyl sulfoxide (DMSO) reductase catalyzes the reduction of dimethyl sulfoxide (DMSO) to dimethyl sulfide (DMS) during anaerobic respiration; it can also use trimethylamine N-oxide (TMAO) as terminal electron acceptor. Subunit B is proposed to be involved in electron transfer.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
