Abstract

We have combined 2-D SDS-PAGE with liquid chromatography-high resolving mass spectrometry (LC-MS) to explore the proteome of the adenovirus type 2 (Ad2) at the level of post translational modifications (PTMs). The experimental design included in-solution digestion, followed by titanium dioxide enrichment, as well as in-gel digestion of polypeptides after separation of Ad2 capsid proteins by 1-D and 2-D SDS-PAGE. All samples were analyzed using LC-MS with subsequent manual verification of PTM positions. The results revealed new phosphorylation sites that can explain the observed trains of protein spots observed for the pIII, pIIIa and pIV proteins. The pIIIa protein was found to be the most highly modified protein with now 18 verified sites of phosphorylation, three sites of nitrated tyrosine and one sulfated tyrosine. Nitrated tyrosines were also identified in pII. Lysine acetylations were detected in pII and pVI. The findings make the Ad2 virion much more complex than hitherto believed.

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.
