This family is found primarily in bacterial surface antigens, normally as variable number repeats at the N-terminus. The C-terminus of these proteins is normally represented by Pfam:PF01103. The alignment centres on a -GY- or -GF- motif. Some members of this family are found in the mitochondria. It is predicted to have a mixed alpha/beta secondary structure.	Domain

This domain is found in bacterial outer membrane lipoproteins probably involved in maintaining the structural integrity of the cell envelope [1], including Outer membrane protein assembly factor BamE from Vibrio cholerae (also known as SmpA). The lipid attachment site is a conserved N terminal cysteine residue. Sometimes found adjacent to the OmpA domain (Pfam:PF00691).	Domain
