DNA binding domain of the motility gene repressor (MogR)
This domain family is found in bacteria, and is approximately 150 amino acids in length. MogR is involved in repression of transcription of the flagellar gene in Listeria bacteria. This allows a phenotypical switch from an extracellular bacterium to an intracellular pathogen. MogR binds AT rich flagellar gene promoter regions upstream of the flagellar gene. These regions follow the pattern 5'-TTTTNNNNNAAAA-3'. This domain is the DNA binding domain of MogR.
