The mobile antibiotic resistance geneblaIMP-1is clinically important and has a synonymous AAA:AAG lysine codon usage bias of 73:27. This bias is like that seen in experimentally determined highly expressed genes inEscherichia coliandAcinetobacter baumanii, but quite different from that seen inPseudomonas aeruginosa(26:74 AAA:AAG). Here we show that, paradoxically, shifting the AAA:AAG lysine codon bias to 8:92 inblaIMP-1expressed from a natural promoter results in significantly more IMP-1 production in all three species. Sequential site directed mutagenesis revealed that increased IMP-1 production occurs following removal of an AAA,AAA double lysine codon and that otherwise, lysine codon usage had no observable impact on IMP-1 production. We conclude that ribosomal slippage at this poly-adenosine region reduces efficient translation of IMP-1 and that punctuating the region with guanine reduces ribosomal slippage and increases IMP-1 production.
