Names: Rrf2-type HTH domain
Function: The rrf2-type HTH domain is a putative DNA-binding, winged
 helix-turn-helix (wHTH) domain of about 130 residues present in transcription
 regulators of the rrf2 family, involved in nitrite or iron metabolism. The
 C-terminal part of the domain contains 3 conserved cysteine residues that may
 bind an Fe-S cluster.
