Codon bias and heterologous protein expression.
The expression of functional proteins in heterologous hosts is a cornerstone of modern biotechnology. Unfortunately, proteins are often difficult to express outside their original context. They might contain codons that are rarely used in the desired host, come from organisms that use non-canonical code or contain expression-limiting regulatory elements within their coding sequence. Improvement...
متن کاملMore Codon Usage Bias
χ measure. In statistics, the χ statstic computes how different the distribution of values is from a uniform distribution. Let d = c1 . . . cN be a DNA string in nucleotide alphabet, and let L be the total number of codons in d that are not Methinine or Tryptophan (the number does include the stop codons though). Let a be a k-degenerate amino acid, and let La be the total number of codons codin...
متن کاملIdentification of Synonymous Codon Usage Bias in the Pseudorabies Virus UL31 Gene
Background: Little knowledge of synonymous codon usage pattern of pseudorabies virus (PRV) genome, especially the UL31 gene in the process for its evolution is available. Objectives: In the present study, the codon usage bias between PRV UL31 sequence and the UL31-like sequences was identified. Materials and Methods: We used a comprehensive analysi...
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 کاملEvolution of codon usage bias in Drosophila.
We first review what is known about patterns of codon usage bias in Drosophila and make the following points: (i) Drosophila genes are as biased or more biased than those in microorganisms. (ii) The level of bias of genes and even the particular pattern of codon bias can remain phylogenetically invariant for very long periods of evolution. (iii) However, some genes, even very tightly linked gen...
