Hypothesis
Using codon-optimized genes may improve recombinant protein expression levels in Escherichia coli.
Conclusion
The codon randomization method is superior for enhancing protein expression compared to the one amino acid-one codon method.
Supporting Evidence
- The codon randomization method produced significantly more proteins than the native sequence.
- One gene variant produced an increase of 70% in prochymosin accumulation.
- No significant improvement was observed for the one amino acid-one codon method.
Takeaway
Scientists tested two ways to change genes to make more protein in bacteria. One way worked much better than the other.
Methodology
Seven sequences encoding calf prochymosin were designed using two codon optimization strategies and expressed in E. coli.
Limitations
The study did not explore the effects of codon optimization on the quality of inclusion bodies in detail.
