Codon-Mutant Libraries of Protein-Coding Genes
Technique that mutates entire genes at the codon level at a controlled rate, compared to existing error-prone PCR methods that achieve this on the nucleotide level
Random mutant libraries of genes are used in a wide variety of molecular biology and bioengineering applications. Current techniques (such as error-prone PCR and its variants) are well suited for introducing mutations at the nucleotide level. PCR with oligonucleotides containing degenerate bases at certain positions are well suited for creating randomized codons at a small number of positions, particularly if these positions are nearly contiguous in primary sequence. However, there are no standard techniques for randomizing codons uniformly throughout a gene at a low rate of mutagenesis. Dr. Bloom has devised an approach to create random codon mutations distributed uniformly across a gene. The Bloom Lab has successfully applied this technique to randomly mutate all codon positions (except the start and stop codons) in the 1.5 kb influenza nucleoprotein gene as proof of concept.
