Effects of GUG and AUG initiation codons on the expression of lacZ in Escherichia coli

We have replaced the ribosomal binding site (RBS) of the lacZ gene of E. coli by those of the maturation (A) gene of phage MS2 and that of the tufA gene. Both RBSs contain a GUG initiation codon. The expression with the tufA RBS is at least 25-fold higher than with the phage RBS. Changing the GUG in...
