An extreme codon preference strategy: codon reassignment.
We argue that in animal mitochondria codon reassignments, such as those for AGA and AGG from arginine to serine or of AUA from isoleucine to methionine, are the result of an interplay between biased mutational forces and selective ones. In particular, there is a marked tendency for animal mitochondria to have very small genomes and to minimize their investment in components required for gene ex...
متن کاملCodon Preference Optimization Increases Heterologous PEDF Expression
Pigment epithelium-derived factor (PEDF) is widely known for its neurotrophic and antiangiogenic functions. Efficacy studies of PEDF in animal models are limited because of poor heterologous protein yields. Here, we redesigned the human PEDF gene to preferentially match codon frequencies of E coli without altering the amino acid sequence. Following de novo synthesis, codon optimized PEDF (coPED...
متن کاملCorrelation between genome size, observed codon preference, and Gibbs energy of codon-anticodon interaction
The universal correspondence between the primary structure of a gene, characterized by a unique sequence of only four different nucleotide residues, and the primary structure of a protein, characterized by a given sequence of twenty different amino acid residues, is known as the "genetic code". This code is degenerated in the sense that a group of six, four or just two synonymous codons can cod...
متن کاملCodon Preference Optimization Increases Prokaryotic Cystatin C Expression
Gene expression is closely related to optimal vector-host system pairing in many prokaryotes. Redesign of the human cystatin C (cysC) gene using the preferred codons of the prokaryotic system may significantly increase cysC expression in Escherichia coli (E. coli). Specifically, cysC expression may be increased by removing unstable sequences and optimizing GC content. According to E. coli expre...
متن کاملCodon usage and gene expression level in Dictyostelium discoideum: highly expressed genes do 'prefer' optimal codons.
Codon usage patterns in the slime mould Dictyostelium discoideum have been re-examined (a total of 58 genes have been analysed). Considering the extreme A + T-richness of this genome (G + C = 22%), there is a surprising degree of codon usage variation among genes. For example, G + C content at silent sites varies from less than 10% to greater than 30%. It was previously suggested [Warrick, H.M....
