Codon usage can affect efficiency of translation of genes inEscherichia coli

Abstract
By inserting synthetic oligonucleotides into a highly expressed gene in E.coli it has been shown that unfavourable codon usage can reduce the maximum translation rate of a protein. However, in the case of the codon used (AGC) a significant effect on translation was only seen at very high transcription rates from a gene containing multiple copies of the unfavourable codon.
