Regulation of the pyrimidine biosynthetic pathway in a pyrD knockout mutant of Pseudomonas aeruginosa.

Abstract excerpt

In research to date, regulation of the pyrimidine biosynthetic pathway at the level of gene expression has not been shown for wild type Pseudomonas aeruginosa. No repression was observed when uracil was added to the growth medium nor was any derepression seen when Pyr(-) auxotrophs were limited for pyrimidines. Here we show that the addition of uracil to Pseudomonas minimal medium influenced the synthesis of...
