Mirror-image T7 transcription of chirally inverted ribosomal and functional RNAs

Xu, Yuan, Zhu, Ting F.·2022·Science

Abstract

To synthesize a chirally inverted ribosome with the goal of building mirror-image biology systems requires the preparation of kilobase-long mirror-image ribosomal RNAs that make up the structural and catalytic core and about two-thirds of the molecular mass of the mirror-image ribosome. Here, we chemically synthesized a 100-kilodalton mirror-image T7 RNA polymerase, which enabled efficient and faithful transcription of the full-length mirror-image 5 S , 16 S , and 23 S ribosomal RNAs from enzymatically assembled long mirror-image genes. We further exploited the versatile mirror-image T7 transcription system for practical applications such as biostable mirror-image riboswitch sensor, long-term storage of unprotected kilobase-long l -RNA in water, and l -ribozyme–catalyzed l -RNA polymerization to serve as a model system for basic RNA research.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
