Abstract

The speed at which RNA molecules decompose is a critical determinant of many biological processes, including those directly involved in the storage and expression of genetic information. One mechanism for RNA cleavage involves internal phosphoester transfer, wherein the 2′-oxygen atom carries out an S N 2-like nucleophilic attack on the adjacent phosphorus center (transesterification). In this article, we discuss fundamental principles of RNA transesterification and define a conceptual framework that can be used to assess the catalytic power of enzymes that cleave RNA. We deduce that certain ribozymes and deoxyribozymes, like their protein enzyme counterparts, can bring about enormous rate enhancements.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • All of these tasks might be performed by RNA, acting either alone or with the help of a suitably positioned metal cation or other cofactor.

    “All of these tasks might be performed by RNA (Narlikar and Herschlag 1997;Emilsson et al. 2003), acting either alone (Strobel and Ortoleva-Donnelly 1999) or with the help of a suitably positioned metal cation or other cofactor (Shan et al. 1999(Shan et al. , 2001)).”

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.
