Conformer-dependent proton-transfer reactions of ubiquitin ions
Abstract
The conformations of ubiquitin ions before and after being exposed to proton transfer reagents have been studied by using ion mobility/mass spectrometry techniques. Ions were produced by electrospray ionization and exposed to acetone, acetophenone, n-butylamine, and 7-methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene. Under the conditions employed, the +4 to +13 charge states were formed and a variety of conformations, which we have characterized as compact, partially folded, and elongated, have been observed. The low charge state ions have cross sections that are similar to those calculated for the crystal conformation. High charge states favor unfolded conformations. The ion mobility distributions recorded after ions have been exposed to each base show that the lowest charge state that is formed during proton-transfer reactions favors a compact conformation. More open conformations are observed for the higher charge states that remain after reaction. The results show that for a given charge state, the apparent gas-phase acidities of the different conformations are ordered as compact < partially folded < elongated.

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.
