ArsR Transcriptional Repressor
Biological function
The gene arsR stems from the E. coli-specific plasmid R773 and encodes for a transcriptional regulator with binding sites for arsenic compounds.

It is a repressor protein that binds to its promoter in the absence of arsenic compounds therefore repressing the expression of downstream genes.

Arsenic compounds that are taken up by bacterial cells form a complex with ArsR, thereby allosterically preventing the association of ArsR with the promoter. Thus, the transcription of downstream genes is induced.
