Transcriptional activator protein BjaR1

Gene

bjaR1

Organism
Bradyrhizobium diazoefficiens (strain JCM 10833 / IAM 13628 / NBRC 14792 / USDA 110)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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.1 Publication
