| Notes | This promoter shows a decrease in transcription during stationary phase, probably due to the very small spacing between topAp4 and topAp5, where binding of sigma-S polymerase to promoter topAp5 might block binding of sigma 70 RNA polymerase. This promoter shows a decrease in transcription during heat shock. |
