Stone, Hyungmin Jun, Xiao Wang, Mark Bathe Department of Biological Engineering, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA; Abstract Structural DNA nanotechnology is beginning to emerge as a widely accessible research tool to mechanistically study diverse biophysical processes. Enabled by scaffolded DNA origami in which a long single strand of DNA is weaved throughout an entire target nucleic acid assembly to ensure its proper folding, assemblies of nearly any geometric shape can now be programmed in a fully automatic manner to interface with biology on the 1–100-nm scale.

The tight and specific assembly between the P5abc and DP5 modules depends on two sets of intermodule interactions. The interface between P5abc and DP5 must be controlled when designing RNA nanostructures. To expand the repertoire of molecular recognition in the P5abc/DP5 interface, we modified the interface by replacing the parent tertiary interactions in the interface with artificial interactions. The engineered P5abc/DP5 interfaces were characterized biochemically to identify those suitable for nanostructure design. The new interfaces were used to construct 2D-square and 1D-array RNA nanostructures. Keywords: catalytic RNA; group I intron; ribozyme; RNA nanostructure; RNA nanotechnology 1. Introduction Nanometer-sized biomolecules and their assemblies with precisely controlled shapes are attractive materials for the expanding field of nanobioscience, which includes nanomedicine and nanobiotechnology.

The sequences for RNA scaffold and DNA staples are given in Figure S1. Both primers and DNA staple strands were purchased from Integrated DNA technology (IDT) and used without further purification. PCR amplification of DNA template: The dsDNA template containing T7 promoter sequence was prepared by polymerase chain reaction (PCR) with a DNA plasmid pUC19 (New England Biolabs), primers (P1 and P2), and GoTaq Flexi DNA polymerase (Promega). In vitro RNA transcription: AmpliScribe™ T7-Flash™ Transcription Kit (Epicentre) was used to transcribe single-stranded RNA from DNA template, following the protocol provided with the kit. Briefly, a total of 20 uL mixture, including DNA template, ribonucleotides, RNase inhibitor together with T7-Flash RNA polymerase, was prepared in the provided reaction buffer, and then incubated at 42 °C for 120 mins. Then, transcription product was treated by DNase I to remove DNA template by incubating at 37 °C for 15 mins. Quantification of RNA scaffold: Purified RNA strands were quantified by a UV-Vis spectrophotometer. RNA strands without purification after in vitro transcription were indirectly quantified through agarose gel electrophoresis by using purified RNA as the calibrator.

ABSTRACT The scaffolded origami technique has provided an attractive tool for engineering nucleic acid nanostructures. This paper demonstrates scaffolded RNA origami folding in vitro in which all components are transcribed simultaneously in a single-pot reaction. Double-stranded DNA sequences are transcribed by T7 RNA polymerase into scaffold and staple strands able to correctly fold in high yield into the nanoribbon.

Afonin Received: 1 July 2020; Accepted: 24 July 2020; Published: 26 July 2020 Abstract: DNA origami nanocarriers have emerged as a promising tool for many biomedical applications, such as biosensing, targeted drug delivery, and cancer immunotherapy. These highly programmable nanoarchitectures are assembled into any shape or size with nanoscale precision by folding a single-stranded DNA scaffold with short complementary oligonucleotides. The standard scaffold strand used to fold DNA origami nanocarriers is usually the M13mp18 bacteriophage’s circular single-stranded DNA genome with limited design flexibility in terms of the sequence and size of the final objects. However, with the recent progress in automated DNA origami design—allowing for increasing structural complexity—and the growing number of applications, the need for scalable methods to produce custom scaffolds has become crucial to overcome the limitations of traditional methods for scaffold production. Improved scaffold synthesis strategies will help to broaden the use of DNA origami for more biomedical applications.

    Algorithmic Design of Cotranscriptionally Folding 2D RNA Origami Structures? Abdulmelik Mohammed1, Pekka Orponen1, and Sachith Pai1 Aalto University, Department of Computer Science FI-00076 Aalto, Finland [email protected], [email protected], [email protected] Abstract. We address a biochemical folding obstacle of \polymerase trapping" that arises in the remarkable RNA origami tile design frame- work of Geary, Rothemund and Andersen (Science 2014). We present a combinatorial formulation of this obstacle, together with an optimisa- tion procedure that yields designs minimising the risk of encountering the corresponding topological trap in the tile folding phase. The procedure has been embedded in an automated software pipeline, and we provide examples of designs produced by the software, including an optimised version of the RNA smiley-face tile proposed by Geary and Andersen (DNA 2014).

In the past few years, there has also been increasing interest in using RNA, rather than DNA, as the fundamental construc- tion material for similar purposes [5, 7{9]. One great appeal of this alternative is that while the production of designed DNA nanostructures typically proceeds by a multi-stage laboratory protocol that involves synthesising the requisite nucleic acid strands and hybridising them together in a thermally controlled process, RNA nanostructures can in principle be produced in quantity by the natu- ral process of polymerase transcription from a representative DNA template, isothermally at room temperature, in vitro and eventually in vivo.
