bluR

Gene
bluR
Protein
HTH-type transcriptional repressor BluR
Organism
Escherichia coli (strain K12)
Length
243 amino acids
Function
Controls the expression of several small proteins that may play a role in biofilm maturation. Binds to and represses the operator of the ycgZ-ymgA-ariR-ymgC operon and also regulates ynaK. Binding is antagonized by BluF upon blue light (470 nm) irradiation. Blue light may increase the affinity of BluF for BluR, allowing it to be released from its operator.
