Evidence for the role of solvated metal hydroxide in the hammerhead cleavage mechanism

Dahm, SueAnn C., Derrick, Wesley B., Uhlenbeck, Olke C.·1993·Biochemistry

Abstract

The log of the rate of the chemical step of hammerhead cleavage in Mg2+ increases linearly with pH between pH 5.7 and 8.9. A slope of approximately 1 indicates that a single deprotonation is required for cleavage. Hammerhead pH-rate profiles with Ca2+, Mn2+, Co2+, and Cd2+ correlate well with the pKa's of these ions in water. This relationship between the pKa's and the pH-rate profile suggests that a metal hydroxide bound to the hammerhead RNA acts as the base in the cleavage mechanism.

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.
