title: The nucleotide sequence of the promoter region of hisS, the structural gene for histidyl-tRNA synthetase.
abstract: A plasmid has been constructed which carries hisS, the structural gene for histidyl-RNA synthetase of E. coli, on a 1.6-kb fragment bounded by PvuII and BstEII sites. The DNA sequence of both ends of this fragment was determined. The amino-terminal sequence of histidyl-tRNA synthetase was also determined to locate the promoter proximal coding region and the frame in which it is read. Three promoters were identified by consensus criteria. The region surrounding these promoters contains extensive twofold symmetry.
