| Abstract |
The effect of two neighboring codons (codon pairs) on gene expression is mediated via the interaction of their cognate tRNAs occupying the two functional ribosomal sites during the translation elongation step. For steric reasons it is reasonable to assume that not all combinations of codons and therefore of tRNAs are equally favorable when situated on the ribosome surface. Aiming of identifying preferential and rare codon pairs, we have determined the frequency of occurrence of all possible combinations of codon pairs in the entire genome of Escherichia coli (E.coli). |
