function; \codon dialect" found for individual unicellular organisms [1]. Taxonomically related organisms have similar dialects but those distantly related have distinct ones. For example, characteristics of E. coli codon{choice (E. coli dialect) di er considerably from those of yeast S. cerevisiae, but are similar to those of Salmonella. By measuring cellular tRNA contents of these three species, we have shown that their codon dialect to be related to the isoaccepting

Identification of Synonymous Codon Usage Bias in the Pseudorabies Virus UL31 Gene
Background: Little knowledge of synonymous codon usage pattern of pseudorabies virus (PRV) genome, especially the UL31 gene in the process for its evolution is available. Objectives: In the present study, the codon usage bias between PRV UL31 sequence and the UL31-like sequences was identified. Materials and Methods: We used a comprehensive analysi...

Expression of foreign proteins in E. coli is normally inhibited by exogenous production of acetate. To overcomethis problem, various strategies have been proposed and tested to reduce the extent of acetate accumulation.Although these strategies can improve the outcome, the implementation of their proposed techniquesis not practical. Because to achieve optimal results, it requi...
