Codon Bias Patterns of E. coli’s Interacting Proteins
Synonymous codons, i.e., DNA nucleotide triplets coding for the same amino acid, are used differently across the variety of living organisms. The biological meaning of this phenomenon, known as codon usage bias, is still controversial. In order to shed light on this point, we propose a new codon bias index, CompAI, that is based on the competition between cognate and near-cognate tRNAs during t...
متن کاملCodon bias patterns in photosynthetic genes of halophytic grass Aeluropus littoralis
Codon bias refers to the differences in the frequency of occurrence of synonymous codons in coding DNA. Pattern of codon and optimum codon utilization is significantly different between the lives. This difference is due to the long term function of natural selection and evolution process. Genetics drift, mutation and regulation of gene expression are the main reasons for codon bias. In this stu...
متن کاملSchistosoma mansoni: patterns of codon usage and bias.
Codon usage and bias has been examined in 20 genes of Schistosoma mansoni. Significant heterogeneity was detected in the patterns of codon usage and bias among genes by metric multidimensional scaling and three general indicators of bias (GC3S, Nc and B). In keeping with observations on sporozoan parasites, codon usage bias was observed to be dependent on the overall base composition of the gen...
متن کاملComparative Analysis of Codon Usage Bias Patterns in Microsporidian Genomes
The sub-3 Mbp genomes from microsporidian species of the Encephalitozoon genus are the smallest known among eukaryotes and paragons of genomic reduction and compaction in parasites. However, their diminutive stature is not characteristic of all Microsporidia, whose genome sizes vary by an order of magnitude. This large variability suggests that different evolutionary forces are applied on the g...
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...
