The Legionella pneumophila chaperonin – an unusual multifunctional protein in unusual locations
Frontiers in Cellular and Infection Microbiology, 2011 The L. pneumophila chaperonin, HtpB, was discovered as a highly immunogenic antigen, only a few years after the identification of L. pneumophila as the causative agent of Legionnaires’ disease.
