Genetic analysis of the alginate biosynthetic gene cluster of <i>Pseudomonas aeruginosa</i> shows evidence of an operonic structure

Abstract excerpt

Strains of Pseudomonas aeruginosa causing pulmonary infections in cystic fibrosis patients have an unusual mucoid phenotype because of production of the capsule-like exopolysaccharide, alginate. Transcriptional activation of algD, the first gene of a large alginate biosynthetic gene cluster, is associated with conversion to the alginate-producing (Alg+) phenotype. In this study, we examined the regulation of...
