Protein
Regulator of sigma D
Organism
Yersinia enterocolitica serotype O:8 / biotype 1B (strain NCTC 13174 / 8081)
Function
Binds RpoD and negatively regulates RpoD-mediated transcription activation by preventing the interaction between the primary sigma factor RpoD with the catalytic core of the RNA polymerase and with promoter DNA. May be involved in replacement of the RNA polymerase sigma subunit from RpoD to RpoS during the transition from exponential growth to the stationary phase.
Similarity
Belongs to the Rsd/AlgQ family.
