Silent mutations in the Shine-Dalgarno-like sequence and the predicted relative translation rates from the first and the second in-frame ATGs. (A) Illustration of the 18-nucleotide region mutated in MMTV gag gene to disrupt the Shine-Dalgarno-like sequence (underlined) 4 nts upstream of the second in-frame ATG (at nucleotide position 1674). These mutated sequences were cloned in both with and without His-tag clones AK7 and AK31, respectively; (B) Bar graphs showing the predicted translation rates from the legitimate first start codon and the second in-frame start codon in the wild type and in AK7(His+) and AK31(His−)-containing a mutated Shine-Dalgarno-like sequence.
