ArsR-like helix-turn-helix domain (IPR011991)

Short name: ArsR-like_HTH

Overlapping homologous superfamilies

Domain relationships


This domain is found in the arsenical resistance operon repressor (ArsR) and similar prokaryotic, metal regulated homodimeric repressors. The ArsR subfamily of helix-turn-helix bacterial transcription regulatory proteins (winged helix topology) includes several proteins that appear to dissociate from DNA in the presence of metal ions [PMID: 8506147, PMID: 9466913, PMID: 11683648, PMID: 10995250].
