merR | BacMet ID: BAC0686Code for: Regulator
Family: Contains 1 HTH merR-type DNA-binding domainSequence: FASTA
Cross-database information: Link
Organism: Serratia marcescensLocation: Plasmid pDU1358 (Serratia marcescens)
Compound: Mercury (Hg)Description: Mediates the mercuric-dependent induction of mercury resistance operon. In the absence of mercury MerR represses transcription by binding tightly to the mer operator region; when mercury is present the dimeric complex binds a single ion and becomes a potent transcriptional activator, while remaining bound to the mer site.
Length (amino acid): 144
