Domain is found in an undescribed set of proteins [1]. Normally occurs uniquely within a sequence, but is found as a tandem repeat (Swiss:Q9X8B8). Shows interesting phylogenetic distribution with majority of examples in bacteria and archaea, but it is also found in some fungal proteins. The hypothetical protein TT1751 from Thermus thermophilus has a beta-alpha-beta(4)-alpha structural fold [2].	Domain
