Directed Evolution of a Panel of Orthogonal T7 RNA Polymerase Variants for in Vivo or in Vitro Synthetic Circuitry

ACS Synth Biol. 2015 Oct 16;4(10):1070-6. doi: 10.1021/sb500299c. Epub 2014 Oct 7.

Abstract

T7 RNA polymerase is the foundation of synthetic biological circuitry both in vivo and in vitro due to its robust and specific control of transcription from its cognate promoter. Here we present the directed evolution of a panel of orthogonal T7 RNA polymerase:promoter pairs that each specifically recognizes a synthetic promoter. These newly described pairs can be used to independently control up to six circuits in parallel.

Keywords: directed evolution; genetic circuits; transcription.
