Nucleotide sequence of the Bacillus subtilis tryptophan operon.

In Bacillus subtilis, tryptophan biosynthesis is one of the most thoroughly characterized biosynthetic pathways. Recombinant DNA methodology has permitted a rapid characterization of the tryptophan (trp) gene cluster at the molecular level. In this report the nucleotide sequence of the six structural genes together with the intercistronic regions and flanking regulatory regions are presented.
