Although the Shine-Dalgarno sequences vary considerably in different genes, they include examples like GAGGGG that could serve

Question:

Although the Shine-Dalgarno sequences vary considerably in different genes, they include examples like GAGGGG that could serve as code-in this case, for Glu-Gly. Does this imply that the sequence Glu-Gly can-not ever occur in a protein, lest it be read as a Shine-Dalgarno sequence? Speculate.
