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.

The Omp85 protein superfamily contains bacterial outer membrane proteins, which can function as protein translocases or as membrane protein assembly factors [1]. The family includes the membrane bound beta barrel of proteins such as BamA and TamA from E. coli.

This domain is found at the N-terminal of the chaperone SurA, a chaperone that assists correct folding of outer membrane proteins (OMPs) in Gram-negative bacteria [1]. This is the helical domain found at the N-terminal of SurA that, together with the C-terminal, forms a core domain which contains OMP binding sites. OMP binding induces conformational changes of SurA domains that protect OMPs from misfolding and aggregation [2]. The C-terminal of the SurA protein folds back and forms part of this domain also but is not included in the current alignment.

Secretion of protein products occurs by a number of different pathways in bacteria. One of these pathways known as the type V pathway was first described for the IgA1 protease [2]. The protein component that mediates secretion through the outer membrane is contained within the secreted protein itself, hence the proteins secreted in this way are called autotransporters. This family corresponds to the presumed integral membrane beta-barrel domain that transports the protein. This domain is found at the C terminus of the proteins it occurs in. The N terminus contains the variable passenger domain that is translocated across the membrane. Once the passenger domain is exported it is cleaved auto-catalytically in some proteins, in others a different protease is used and in some cases no cleavage occurs [1].
