The transcription start site is located at the 12th nucleotide after the first nucleotide of the -10 box.
 
A consensus sequence for the ribosome binding site is gagg.
 
The first half of the terminator “hairpin” is aaaaggt, where the u in the mRNA binds with a g instead of the usual a.
 
The terminator includes 4 more nucleotides after the hairpin completes.
