Transcription factors activating transcription at SigL-dependent promoters

These transcription activators control 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

• LevR: control of fructose utilization (levD-levE-levF-levG-sacC)

Unknown activator

• YplP: required for growth at low temperatures
