Abstract

In the past decades, RNA molecules have emerged as important players in numerous cellular pro-cesses. To understand these processes at the mo-lecular and atomic level, large amounts of homogeneous RNA are required for structural, biochemical and pharmacological investigations. Such RNAs are generally obtained from laborious and costly in vitro transcriptions or chemical syn-thesis. In 2007, a recombinant RNA technology has been described for the constitutive production of large amounts of recombinant RNA in Escherichia coli using a tRNA-scaffold approach. We demon-strate a general applicable extension to the described approach by introducing the following im-provements: (i) enhanced transcription of large recombinant RNAs by T7 RNA polymera...
