Abstract:
In Mycoplasma pneumoniae, the UGA opal codon specifies tryptophan rather than a translation stop site. This often makes it difficult to express Mycoplasma proteins in E. coli isolates. In this work, we developed a strategy for the one-step introduction of several mutations. This method, the multiple-mutation reaction, is used to simultaneously replace nine opal codons in the M. pneumoniae glpK gene.
