This domain, found in various hypothetical prokaryotic proteins, has no known function. An aminopeptidase domain is conserved within the family, but its relevance has not been established yet. Rebuilding from PDB:3kt9 shows this is an inserted (nested domain within the amino-peptidase). The function of this small domain is not known.	Domain

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
