Structure of a hemolysin-coregulated protein from Pseudomonas aeruginosa
Overview
Bacterial pathogens frequently use protein secretion to mediate, interactions with their hosts. Here we found that a virulence locus, (HSI-I) of Pseudomonas aeruginosa encodes a protein secretion apparatus., The apparatus assembled in discrete subcellular locations and exported, Hcp1, a hexameric protein that forms rings with a 40 angstrom internal, diameter. Regulatory patterns of HSI-I suggested that the apparatus, functions during chronic infections. We detected Hcp1 in pulmonary, secretions of cystic fibrosis (CF) patients and Hcp1-specific antibodies, in their sera. Thus, HSI-I likely contributes to the pathogenesis of P., aeruginosa in CF patients. HSI-I-related loci are widely distributed among, bacterial pathogens and may play a general role in mediating host, interactions.
