WebThe 30S subunit binds to the mRNA template at a purine-rich region (the Shine-Dalgarno sequence) upstream of the AUG initiation codon. The Shine-Dalgarno sequence is complementary to a pyrimidine rich region on the 16S rRNA component of the 30S subunit. The 30S subunit is an integral part of mRNA translation. It binds three prokaryotic initiation factors: IF-1, IF-2, and IF-3. A portion of the 30S subunit (the 16S rRNA) guides the initiating start codon (5′)-AUG-(3′) of mRNA into position by recognizing the Shine-Dalgarno sequence, a complementary binding site about 8 base pairs upstream from the start codon. This ensures the ribosome starts translation at the co…
