Nucleotide Sequence in the Promoter Region of the Escherichia coli Tyrosine tRNA Gene

The sequence of 29 nucleotides immediately preceding the starting point of transcription of the E. coli tyrosine tRNA gene has been determined. This is: Formula: see text The sequence contains regions of 2-fold symmetry. Transcription of the gene begins at the first nucleotide to the left of nucleotide 1 and is leftward.
