Protein
Transcriptional activator protein BjaR1
Organism
Bradyrhizobium diazoefficiens (strain JCM 10833 / IAM 13628 / NBRC 14792 / USDA 110)
Function
Transcriptional activator that functions in response to the quorum-sensing autoinducer IV-HSL (isovaleryl-homoserine lactone). Activates BjaI expression. Is sensitive to IV-HSL at concentrations as low as 10 pM.
Similarity
Belongs to the autoinducer-regulated transcriptional regulatory protein family.
