Reassigning cysteine in the genetic code of Escherichia coli.
We investigated directed deviations from the universal genetic code. Mutant tRNAs that incorporate cysteine at positions corresponding to the isoleucine AUU, AUC, and AUA and methionine AUG codons were introduced in Escherichia coli K12. Missense mutations at the cysteine catalytic site of thymidylate synthase were systematically crossed with synthetic suppressor tRNACys genes coexpressed from ...
متن کاملRare codon content affects the solubility of recombinant proteins in a codon bias-adjusted Escherichia coli strain
BACKGROUND The expression of heterologous proteins in Escherichia coli is strongly affected by codon bias. This phenomenon occurs when the codon usage of the mRNA coding for the foreign protein differs from that of the bacterium. The ribosome pauses upon encountering a rare codon and may detach from the mRNA, thereby the yield of protein expression is reduced. Several bacterial strains have bee...
متن کاملIdentification of Biofilm Encoding Genes (agg) in the Escherichia coli Isolates by Multiplex-PCR Method
Introduction: Biofilm is a collection of microbial cells that are irreversibly suppressed and mildly washed away. The aggR gene is located on the main plasmid (pAA), which codes for many actuator factors. The pathogen strains of EAEC have an aggR gene, the gene has been identified in six classes of pathogenic E. coli. Materials & Methods: In the present study, 60 stool samples from children ...
متن کاملComparative Mitogenomics of Plant Bugs (Hemiptera: Miridae): Identifying the AGG Codon Reassignments between Serine and Lysine
Insect mitochondrial genomes are very important to understand the molecular evolution as well as for phylogenetic and phylogeographic studies of the insects. The Miridae are the largest family of Heteroptera encompassing more than 11,000 described species and of great economic importance. For better understanding the diversity and the evolution of plant bugs, we sequence five new mitochondrial ...
متن کاملReassignment of a rare sense codon to a non-canonical amino acid in Escherichia coli
The immutability of the genetic code has been challenged with the successful reassignment of the UAG stop codon to non-natural amino acids in Escherichia coli. In the present study, we demonstrated the in vivo reassignment of the AGG sense codon from arginine to L-homoarginine. As the first step, we engineered a novel variant of the archaeal pyrrolysyl-tRNA synthetase (PylRS) able to recognize ...
