Sequences and structures in the mRNA can alter the accuracy of translation. In some cases, mRNA secondary structures like hairpin loops or pseudoknots can cause frequent errors of translational reading frame (programmed frameshifting) or misreading of termination codons as sense (nonsense readthrough). In other cases, the primary mRNA sequence stimulates the error probably by interacting with an element of the ribosome to interfere with error correction. One such primary mRNA sequence, the Ty3 stimulator, increases programmed +1 frameshifting 7.5 times in the yeast Saccharomyces cerevisiae. Here we show that this stimulator also increases the usage of non-AUG initiation codons in the bacterium Escherichia coli but not in S. cerevisiae. These data suggest that in E. coli, though not in yeast, an element of the ribosome's elongation accuracy mechanism ensures initiation accuracy.
