High-fidelity PCR enzyme with DNA-binding domain facilitates de novo gene synthesis.

ABSTRACT: Nowadays enzymatic synthesis of genes is the most powerful tool for fast resolution of the various tasks in the field of basic and applied biological research. PCR-based gene assembly from overlapping oligonucleotides has become a widely used strategy. However, all the methods described in the literature are not perfect and need an extra processing step. In this study we are verifying Phusion high-fidelity polymerase as a tool to reduce nucleotide mismatches in de novo gene synthesis, thus facilitating subsequent cloning. To test the efficiency of the polymerase, we selected Fel d 4 gene, which is a 581 bp DNA sequence encoding the lipocalin allergen protein, one of the major cat allergens. The approach described here, therefore, would be useful in DNA sequences creation.
