Defects in motility and development of Myxococcus xanthus lipopolysaccharide mutants.

abstract：:Cystic fibrosis (CF) patients are highly susceptible to chronic pulmonary disease caused by mucoid Pseudomonas aeruginosa strains that overproduce the exopolysaccharide alginate. We showed here that a mutation in zwf, encoding glucose-6-phosphate dehydrogenase (G6PDH), leads to a approximately 90% reduction in alginat...

abstract：:The nucleotide sequence of the agp gene, which encodes a periplasmic glucose-1-phosphatase, was determined. The deduced amino acid sequence corresponds to a 413-amino-acid-residue polypeptide with a typical hydrophobic signal sequence of 22 amino acids. The mature protein lacks the N-terminal signal peptide and has a ...
