2003-01-01 · In the apoA-I cDNA coding sequence, five codons were changed to the optimal CTG codon (corresponding to Leu46, Leu47, Leu126, Leu214, and Leu233). These changes included elimination of the two low frequency CTA codons present and increased the total number of high abundance CTG codons in the apoA-I cDNA to 25 of 37 total Leu codons. To generate plasmids without a luciferase start codon, NotI–NarI fragments from the pGL2 derivatives carrying (CTG) n repeats in their 5′-UTRs were replaced with synthetic DNA sequences lacking the AUG codon but otherwise identical to the original fragments. TTG, and CTG start codons. Surprisingly, constructs using a TTG start codon showed the best activity, whereas those using ATG or GTG were approximately one-half or one-third as active, respectively. The CTG fusion showed only 5% of the activity of the TTG fusion.

Degeneracy is a hallmark of biological systems. Just as multiple codons are decoded with the same amino acid, CUG start codons may be decoded by more than one initiator tRNA. We propose that the Significantly, CTG codons were the most frequent CTN codons in codon-triplets that vanished from C. albicans and D. hansenii ORFeomes (Additional file 1, Figure S4A). Moreover, in D. hansenii the number of codon-triplets that vanished only from that ORFeome and lacked CTGs was two fold higher than in the other fungi, including C. albicans (Additional file 1 , Figure S4B). A high percentage of Candida albicans CTG codons are represented by serine residues in the Saccharomyces cerevisiae and Schizosaccharomyces pombe genomes.

V. GTT, GTC, GTA, GTG. Phenylalanine. F. One reason could be codon bias. A look at the genetic code (see Table) reveals that there are multiple codons for several amino acids. For example Arg, Leu, and These triplets are called codons.With three exceptions, each codon encodes for one of the 20 amino acids used in CTG, Leu, CCG, Pro, CAG, Gln, CGG, Arg. The fact that codons consist of three DNA bases was first demonstrated in the Crick, Brenner et al.

While DNA can be decoded unambiguously, it is not possible to predict a DNA sequence from its protein sequence.
