DOI: 10.1155/2016/7316725

[…] d cleavages plus a number of variable modifications such as oxidation (M), hypusinylation (K), and deoxyhypusinylation (K). Peptide hits returned by Mascot were manually validated and annotated using xiSPEC (http://spectrumviewer.org/). […]


Protein RNA linkage and posttranslational modifications of feline calicivirus and murine norovirus VPg proteins

PMCID: 4928471

[…] spho (ST), phospho (Y), pAp (STY), pGp (STY), pCp (STY) and pUp (STY). For both viruses at least two independent biological samples were analyzed. For publication the spectra were auto-annotated with xiSPEC (http://spectrumviewer.org) and images were prepared using Inkscape (http://www.inkscape.org). The levels of viral RNA present in the samples used for mass spec were not routinely quantified, h […]


Mto2 multisite phosphorylation inactivates non spindle microtubule nucleation complexes during mitosis

[…] e data set was considered being too small for meaningful FDR estimation using the target-decoy method. Mto2 hits were manually validated, the weakest having a posterior error probability of PEP=0.013.XiSPEC Spectrum Viewer (http://spectrumviewer.org/) was used to visualize MS2 spectra for figure presentation.

Deletion of Genes Encoding Arginase Improves Use of “Heavy” Isotope Labeled Arginine for Mass Spectrometry in Fission Yeast

PLoS One
PMCID: 4468061
PMID: 26075619
DOI: 10.1371/journal.pone.0129548

[…] FT MS/MS was set to 1.0E+05 ions. The maximum allowed time for ion accumulation were 500 ms and 200 ms, respectively.The generated peak lists were searched against protein databases using Mascot 2.0. XiSPEC Spectrum Viewer (http://spectrumviewer.org/) was used to visualize MS/MS spectra for figure presentation. Due to XiSPEC software design, occasionally b or y ions that are indicated in the pepti […]
