A robust strategy for overexpression of DNA polymerase from Thermus aquaticus using an IPTG-independent autoinduction system in a benchtop bioreactor.

The DNA polymerase derived from Thermus aquaticus is the most widely utilized among various DNA polymerases, indicating its significant economic importance. Consequently, efforts to achieve a substantial yield of Taq DNA polymerase (Taq-pol) are ongoing. The expression of recombinant protein using T7-induced promoters presents challenges in cost-effectiveness, primarily due to the reliance on traditional induction method.

An efficient approach for overproduction of DNA polymerase from Pyrococcus furiosus using an optimized autoinduction system in Escherichia coli.

High fidelity DNA polymerase from Pyrococcus furiosus (Pfupol) is an attractive alternative to the highly popular DNA polymerase from Thermus aquaticus. Because this enzyme is in great demand for biotechnological applications, optimizing Pfupol production is essential to supplying the industry's expanding demand. T7-induced promoter expression in Escherichia coli expression systems is used to express recombinant Pfupol; however, this method is not cost-effective.
