Mistranslation in IGF-1 during over-expression of the protein in Escherichia coli using a synthetic gene containing low frequency codons.

Partial misincorporation of Lys for Arg has been observed for the Arg residues of IGF-1 when the molecule is expressed in Escherichia coli using a synthetic gene with the low frequency AGA codon encoding all six Arg residues and yeast preferred codons encoding the remaining residues. The Lys for Arg substitution at these residues could not be detected when a gene containing E. coli preferred codons, with the codon CGT coding for all Arg residues, was used for the expression of the protein. Similarly, no misincorporation of Lys for Arg could be detected when a gene containing Escherichia coli preferred codons at all positions, except for an AGA codon at Arg (36), was utilized.[1]
