1.B.12.4.4
Autotransporter-1, Pet (serine protease; 1295 aas)) (Eslava et al., 1998; Leyton et al., 2010).  The first stage of autotransporter folding determines whether subsequent translocation can deliver the N-terminal domain to its functional form on the bacterial cell surface. Paired conserved glycine-aromatic 'mortise and tenon' motifs join neighbouring beta-strands in the C-terminal barrel domain, and mutations within these motifs slow the rate and extent of passenger domain translocation to the surface of bacterial cell (Leyton et al. 2014).
