A	PF16221	winged helix-turn-helix (HTH_47)	winged helix-turn-helix	HTH_47 is an example of a circularly permuted winged helix-turn-helix domain. HTH_47 is found at the very C-terminus of DUF2172, which is structurally similar to M28-peptidases but lacking one of the key zinc-binding residues.	Domain
