The type III secretion system (T3SS) of Pseudomonas aeruginosa is a key virulence determinant whose expression is induced by polyamine signals from mammalian host. SpuD and SpuE were postulated to be spermidine-preferential binding proteins, which regulate the polyamine content in this bacterial pathogen ...
