Engineering of novel DNA polymerase variants for single enzyme quantitative multiplex reverse transcription-PCR.

ABSTRACT: Reverse transcription polymerase chain reaction (RT-PCR) has evolved as a widely used approach in biotechnology and molecular diagnostics. It represents a powerful tool for amplifying and analysing RNA molecules and has therefore found widespread applications in profiling gene expression, viral detection and the diagnosis of various diseases. Wellestablished methodologies use viral reverse transcriptases (RTs) to transcribe RNA to cDNA and thermostable DNA polymerases (DNA pols) to amplify the resulting target sequence by PCR. This study reports on the development of novel Thermus aquaticus DNA polymerase I (Taq pol) variants that each are able to catalyse both steps simultaneously in a single tube without the need of viral RTs. In combination with their excellent thermostability (up to 95
