Many pathogenic Gram-negative bacteria use type III secretion systems (T3SS) to deliver effector proteins into the host cell cytosol and facilitate the infectious process. The effector protein ExoU from Pseudomonas aeruginosa, one of the most aggressive toxins injected by a T3SS, has four distinct domains. The chaperone-binding domain consists of two separate regions, a N-terminal region and a middle subdomain (this entry). The latter shows a mostly alpha-helical structure [1-3].
This domain is found in the toxin ExoU from Pseudomonas aeruginosa, an effector of the type III secretion system of the bacteria. ExoU is a patatin-like phospholipase that binds to the host membranes and induces cytotoxic effects leading to rapid nec ...
This domain is found in the toxin ExoU from Pseudomonas aeruginosa, an effector of the type III secretion system of the bacteria. ExoU is a patatin-like phospholipase that binds to the host membranes and induces cytotoxic effects leading to rapid necrotic cell death. This protein shows four domains: a putative chaperone binding domain. a patatin-like domain (Pfam:PF01734), and two domains that form the membrane localization domain (MLD). This entry represents the C-terminal domain, which folds into a four-helical bundle with a conserved arginine exposed. This residue seems to be essential for localization [1-3].
