Abstract
Salmonella spp. encode five type VI secretion systems (T6SS) in different pathogenicity islands. These systems translocate effector proteins into target cells, which can be either eukaryotic or prokaryotic. Hcps (hemolysin-coregulated proteins) are components of T6SS and have several functions. The main one is structural, in which hexamers of Hcps form the tube that is ejected towards the…
