Multiple promoters and induction by heat shock of the gene encoding the alternative sigma factor AlgU (sigma E) which controls mucoidy in cystic fibrosis isolates of Pseudomonas aeruginosa.

Abstract excerpt

Overproduction of the exopolysaccharide alginate causes mucoid colony morphology in Pseudomonas aeruginosa and is considered a major virulence determinant expressed by this organism during chronic respiratory infections in cystic fibrosis. One of the principal regulatory elements governing conversion to mucoidy in P. aeruginosa is AlgU, an alternative sigma factor which is 66% identical to and functionally...
