Identification and characterization of genes for a second anthranilate synthase in Pseudomonas aeruginosa: interchangeability of the two anthranilate synthases and evolutionary implications.
Two anthranilate synthase gene pairs have been identified in Pseudomonas aeruginosa. They were cloned, sequenced, inactivated in vitro by insertion of an antibiotic resistance gene, and returned toExpand

The complete nucleotide sequence of the tryptophan operon of Escherichia coli.
The tryptophan (trp) operon of Escherichia coli has become the basic reference structure for studies on tryptophan metabolism. Within the past five years the application of recombinant DNA andExpand

An apparent Bacillus subtilis folic acid biosynthetic operon containing pab, an amphibolic trpG gene, a third gene required for synthesis of para-aminobenzoic acid, and the dihydropteroate synthase
McDonald and Burke (J. Bacteriol. 149:391-394, 1982) previously cloned a sulfanilamide-resistance gene, sul, residing on a 4.9-kb segment of Bacillus subtilis chromosomal DNA, into plasmid pUB110. InExpand

Evolutionary differences in chromosomal locations of four early genes of the tryptophan pathway in fluorescent pseudomonads: DNA sequences and characterization of Pseudomonas putida trpE and trpGDC.
Pseudomonas putida possesses seven structural genes for enzymes of the tryptophan pathway. All but one, trpG, which encodes the small (beta) subunit of anthranilate synthase, have been mapped on theExpand

DNA sequences and characterization of four early genes of the tryptophan pathway in Pseudomonas aeruginosa.
Two pairs of related but easily distinguishable genes for the two subunits of anthranilate synthase have been identified in Pseudomonas aeruginosa. These were cloned, sequenced, inactivated in vitroExpand

In vitro determination of the effect of indoleglycerol phosphate on the interaction of purified TrpI protein with its DNA-binding sites.
Expression of the trpBA gene pair of Pseudomonas aeruginosa is regulated by the endogenous level of indoleglycerol phosphate (InGP) and the trpI gene product. The TrpI protein binds to the -77 to -32Expand

The Rhizobium meliloti trpE(G) gene is regulated by attenuation, and its product, anthranilate synthase, is regulated by feedback inhibition.
In Rhizobium meliloti, the genes involved in biosynthesis of the amino acid tryptophan are found at three separate chromosomal locations. Of the three gene clusters, trpE(G), trpDC, and trpFBA, onlyExpand
