Abstract
Several Legionella pneumophila proteins were highly expressed in low-temperature supernatants. One of these proteins was the peptidyl-prolyl isomerase PpiB. Mutants lacking ppiB exhibited reduced growth at 17 degrees C. Since PpiB lacked a signal sequence and was present in 17 degrees C supernatants of type II and type IV secretion mutants, this protein may be secreted by a novel mechanism.Entities:
