Abstract

We describe the application of the hydroxyl radical footprinting technique to examine the histone-DNA interactions of a nucleosome that includes part of the 5S ribosomal RNA gene of Xenopus borealis. We establish that two distinct regions of DNA with different helical periodicities exist within the nucleosome and demonstrate a change in the helical periodicity of this DNA upon nucleosome formation. In particular, we find that on average the helical periodicity of DNA in this nucleosome is 10.18 +/- 0.05 base pairs per turn. The same DNA, when bound to a calcium phosphate surface, has a periodicity of 10.49 +/- 0.05 base pairs per turn, similar to that of random sequence DNA. Modulations in minor groove width within the naked DNA detected by the hydroxyl radical are maintained and exaggerated in nucleosomal DNA. These features correlate with regions in the DNA previously suggested to be important for nucleosome positioning.

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.
