This entry represents the N-terminal domain found in serine protease autotransporters Pic, sepA, espP and espC and immunoglobulin A1 protease autotransporter (IgA1) from bacteria. These proteins have been found in virulent strains and are considered virulence factors [1, 2]. Pic and other bacterial autotransporters confer serum resistance even although they do not degrade immunoglobulin [1,3] as in the case of IgA1 [4]. This domain has protease activity [1,5,6].	Domain
