50+ E Coli Codon Usage Table Images. Escherichia coli and salmonella, vol. Jump to navigationjump to search.
Escherichia coli, originally known as bacterium coli commune, was identified in 1885 by the german pediatrician, theodor escherich (14, 29).
Not all 61 mrna codons are used equally. The e.coli translational machinery codes for all aa, but it might have low abundance for some of the trnas utilized by the codons of the human protein. Correlation between the abundance of escherichia coli transfer rnas and the occurrence of the respective codons in its protein genes. Highly conserved sites and genes have higher codon bias than less conserved ones, and codon bias is positively correlated to gene length.
