for high-throughput production of recombinant protein in escherichia coli ( e. coli ), besides important parameters such as efficient vector with strong promoter and compatible host, other important issues including codon usage, rare codons, and gc content specially at n-terminal region should be considered. in the current study, the effect of decreasing the percentage of gc nucleotides and opt...
by application of modern recombinant dna technology, especially the polymerase chain reaction (pcr)/dot-blot hybridization techniques, we have investigated the molecular basis of β-thalassemia from four different regions of iran: central, south-east, south and north. in this study, the dna samples were isolated from patients and for the identification of the mutations, the 6 oligonucleotide pro...
Codon pair bias is a remarkably stable characteristic of a species. Although functionally uncharacterized, robust virus attenuation was achieved by recoding of viral proteins using underrepresented codon pairs. Because viruses replicate exclusively inside living cells, we posited that their codon pair preferences reflect those of their host(s). Analysis of many human viruses showed, however, th...
Synonymous codon choices at the beginning of genes optimize 5' RNA structures for enhanced translation initiation, but less is known about mechanisms that drive codon optimization downstream within the gene. To understand what determines codon choices across a gene, we generated 12,726 in situ codon mutants in the Escherichia coli essential gene infA and measured their fitness by combining mult...
A novel combination of three codon inserts in the pol coding region of HIV-1 RNA was identified in a highly antiretroviral experienced study subject with HIV-1 infection. A one codon insert was observed in the protease region between codon 40 and 41 simultaneously with a two codon insert present in the reverse transcriptase region at codon 69.
