Arsenic Promoter (ArsR regulated)


This set includes promoters that are sensitive to various metals. The promoters are typically regulated by a receptor protein that binds to the metal ion or complex.

Promoter sequence with recognition site for ArsR transcriptional regulator protein. ArsR binds to the promoter sequence in the absence of As and releases on binding of As, thereby activating transcription (1).
