The organization and nucleotide sequence of the Bacillus subtilis hisH, tyrA and aroE genes.

ABSTRACT

The nucleotide sequence of approximately 3 kb of Bacillus subtilis DNA distal to the trp operon was determined. Three open reading frames were found and these were shown to encode the hisH, tyrA and aroE genes. Integrative plasmids were constructed to interrupt transcription through this region. These data suggest that these three genes can be transcribed from both the trp promoter preceding the trp operon and from a promoter within the trpA structural gene.
