Domain of unknown function (DUF2172)
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 Structure 3kt9 shows this is an inserted (nested domain within the amino-peptidase). The function of this small domain is not known.
