Description
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
[4, 3]. This superfamily corresponds to the presumed integral membrane β-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, 4].
