The reactivity of phosphodiester bonds within linear single-stranded oligoribonucleotides is strongly dependent on the base sequence

Abstract

The cleavage of short chimeric oligonucleotides containing only one reactive ribonucleoside unit, all other nucleosides being 2'-O-methylated, has been studied at pH 8.5 and 35 degrees C. Among the 20 different sequences that did not exhibit any tendency to form a defined secondary structure, the scissile 5'-UpA-3' and 5'-CpA-3' phosphodiester bonds experienced >100- and up to 35-fold reactivity differences, respectively. Compared with dinucleoside monophosphates, both rate accelerations and retardations of more than one order of magnitude were observed. Even a change of a single base several nucleosides away from the scissile bond markedly affected the reaction rate. Duplex formation at the 3'- and/or 5'-side of the scissile bond was also studied and observed to be strongly rate retarding. The origin of the high sensitivity of phosphodiester bonds to the molecular environment is discussed.

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

  • Independent of the nucleotide identity 5' of the U, the bond leading to 3' U is a hotspot for in-line nucleophilic attack.

    “Thus, independent of the nucleotide identity 5’ of the U, this bond is a hotspot for in-line nucleophilic attack63,65.”

    From Combinatorial optimization of mRNA structure, stability, and translation for RNA-based therapeutics (2022) · cites this paper as [63]

    The Results (page unavailable) report that cleavage of the studied 5′-UpA-3′ bond varies strongly with the surrounding sequence; in one sequence, no reaction was detected in three months. The Discussion (page unavailable) explicitly rejects the idea that this bond is inherently prone to cleavage. The paper studies a bond following U, rather than establishing that a bond leading to 3′ U is a hotspot independent of the preceding nucleotide. (LLM, conf=0.82)

  • The base sequence and secondary structure of mRNA influence the rate of hydrolysis.

    “In two publications on mRNA hydrolysis the authors state that the base sequence and secondary structure of mRNA influence the rate of hydrolysis (Kaukinen et al., 2002, Mikkola et al., 2001).”

  • Base-stacking may decrease the cleavage rate of phosphodiester bonds.

    “Specifically, base-stacking may decrease the cleavage rate of phosphodiester bonds.”

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.
