These transcription factors activate transcription at SigL-dependent promoters. RNA polymerase containing SigL is inactive unless productive interaction with an activator protein occurs. Therefore, SigL-dependent genes are among the most strongly regulated genes in B. subtilis.

Activators controlled by interaction with low molecular weight effectors

  • AcoR: control of acetoin utilization (acoA-acoB-acoC-acoL)
  • BkdR: control of the utilization of branched chain amino acids
  • RocR: control of the utilization of arginine, ornithine and citrulline (rocA-rocB-rocC, rocD-rocE-rocF, rocG)

Activator controlled by PTS-dependent phosphorylation

Unknown activator

  • YplP: required for growth at low temperatures
