| pubmed-article:9535088 | pubmed:abstractText | We determined the in vivo translational efficiency of 'unleadered' lacZ compared with a conventionally leadered lacZ with and without a Shine-Dalgarno (SD) sequence in Escherichia coli and found that changing the SD sequence of leadered lacZ from the consensus 5'-AGGA-3' to 5'-UUUU-3' results in a 15-fold reduction in translational efficiency; however, removing the leader altogether results in only a twofold reduction. An increase in translation coincident with the removal of the leader lacking a SD sequence suggests the existence of stronger or novel translational signals within the coding sequence in the absence of the leader. We examined, therefore, a change in the translational signals provided by altering the AUG initiation codon to other naturally occurring initiation codons (GUG, UUG, CUG) in the presence and absence of a leader and find that mRNAs lacking leader sequences are dependent upon an AUG initiation codon, whereas leadered mRNAs are not. This suggests that mRNAs lacking leader sequences are either more dependent on perfect codon-anticodon complementarity or require an AUG initiation codon in a sequence-specific manner to form productive initiation complexes. A mutant initiator tRNA with compensating anticodon mutations restored expression of leadered, but not unleadered, mRNAs with UAG start codons, indicating that codon-anticodon complementarity was insufficient for the translation of mRNA lacking leader sequences. These data suggest that a cognate AUG initiation codon specifically serves as a stronger and different translational signal in the absence of an untranslated leader. | lld:pubmed |
