Cable (cbl) type II pili of cystic fibrosis-associated Burkholderia (Pseudomonas) cepacia: nucleotide sequence of the cblA major subunit pilin gene and novel morphology of the assembled appendage fibers

Abstract excerpt

Previous studies have shown that appendage pili of Burkholderia cepacia strains isolated from patients with cystic fibrosis (CF) at The Hospital for Sick Children, Toronto, Canada, mediate adherence to mucus glycoproteins and also enhance adherence to epithelial cells. The specific pilin-associated adhesin molecule is a 22-kDa protein. In the present study we purified the major subunit pilin (17 kDa) and...
