Successful lateral transfer requires codon usage compatibility between foreign genes and recipient genomes.
We present evidence supporting the notion that codon usage (CU) compatibility between foreign genes and recipient genomes is an important prerequisite to assess the selective advantage of imported functions, and therefore to increase the fixation probability of horizontal gene transfer (HGT) events. This contrasts with the current tendency in research to predict recent HGTs in prokaryotes by as...
متن کاملCodon usage and lateral gene transfer in Bacillus subtilis.
Bacillus subtilis possesses three classes of genes, differing by their codon preference. One class corresponds to prophages or prophage-like elements, indicative of the existence of systematic lateral gene transfer in this organism. The nature of the selection pressure that operates on codon bias is beginning to be understood.
متن کاملComparative Analysis of Codon Usage Bias and Codon Context Patterns between Dipteran and Hymenopteran Sequenced Genomes
BACKGROUND Codon bias is a phenomenon of non-uniform usage of codons whereas codon context generally refers to sequential pair of codons in a gene. Although genome sequencing of multiple species of dipteran and hymenopteran insects have been completed only a few of these species have been analyzed for codon usage bias. METHODS AND PRINCIPAL FINDINGS Here, we use bioinformatics approaches to a...
متن کاملFactors Influencing Codon Usage Bias in Genomes
O código genético é degenerado, isto é, o mesmo amino ácido pode ser codificado por vários codons. Apesar de codificarem o mesmo amino ácido, estes codons sinônimos não são utilizados da mesma forma em genomas diferentes, e mesmo em um único genoma o padrão de uso dos codons sinônimos pode variar muito entre os genes, ou ainda ao longo de um único gene. Com a recente introdução de seqüências ge...
متن کاملCodonExplorer: an online tool for analyzing codon usage and sequence composition, scaling from genes to genomes
DNA composition in general, and codon usage in particular, is crucial for understanding gene function and evolution. CodonExplorer, available online at http://bmf.colorado.edu/codonexplorer/, is an online tool and interactive database that contains millions of genes, allowing rapid exploration of the factors governing gene and genome compositional evolution and exploiting GC content and codon u...
