The chemical repertoire of natural ribozymes

Doudna, Jennifer A., Cech, Thomas R.·2002·Nature

Abstract

Although RNA is generally thought to be a passive genetic blueprint, some RNA molecules, called ribozymes, have intrinsic enzyme-like activity--they can catalyse chemical reactions in the complete absence of protein cofactors. In addition to the well-known small ribozymes that cleave phosphodiester bonds, we now know that RNA catalysts probably effect a number of key cellular reactions. This versatility has lent credence to the idea that RNA molecules may have been central to the early stages of life on Earth.

  • Today, RNA serves as the sole genetic molecule in many viruses.

    “Today, RNA serves as the sole genetic molecule in many viruses, and the number of reactions catalyzed by RNA enzymes (“ribozymes”) is ever increasing (Doudna and Cech, 2002; Chen et al., 2007).”

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.
