PF09102Exotoxin A, targeting (Exotox-A_target)Exotoxin A, targetingMembers of this family are found in Pseudomonas aeruginosa exotoxin A, and are responsible for transmembrane targeting of the toxin, as well as transmembrane translocation of the catalytic domain into the cytoplasmic compartment. A furin cleavage sit ...Members of this family are found in Pseudomonas aeruginosa exotoxin A, and are responsible for transmembrane targeting of the toxin, as well as transmembrane translocation of the catalytic domain into the cytoplasmic compartment. A furin cleavage site is present within the domain: cleavage generates a 37 kDa carboxy-terminal fragment, which includes the enzymatic domain, which is then is translocated into the cytoplasm. The domain adopts a helical structure, with six alpha-helices forming a bundle [1].

The domain adopts a thirteen-strand antiparallel beta jelly roll topology, which belongs to the Concanavalin A-like lectins/glucanases fold superfamily [1].
Domain
PF09009Exotoxin A catalytic (Exotox-A_cataly)Exotoxin A catalyticMembers of this family, which are found in prokaryotic exotoxin A, catalyse the transfer of ADP ribose from nicotinamide adenine dinucleotide (NAD) to elongation factor-2 in eukaryotic cells, with subsequent inhibition of protein synthesis [1].Domain
