Protein

Anaerobic nitric oxide reductase transcription regulator NorR

Gene

norR

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Required for the expression of anaerobic nitric oxide (NO) reductase, acts as a transcriptional activator for at least the norVW operon. Activation also requires sigma-54. Not required for induction of the aerobic NO-detoxifying enzyme NO dioxygenase. Binds to the promoter region of norVW, to a consensus target sequence, GT-(N7)-AC, which is highly conserved among proteobacteria.2 Publications

Domaini

Deletion of amino acids 30-164 allows induction of NO reductase activity even in the absence of NO, i.e. the need for an NO-induced signal has been bypassed.

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.
