[…] (thermo scientific). hiv-1 peptides were identified by using sequest in proteome discoverer software (thermo fisher scientific, version 2.2). the intact env glycopeptides were identified using gpquest [, ]. to quantify the glycosylation in different mutants label-free quantification of env peptides and glycopeptides was done using thermo sieve software version 2.1 (). the data […]

[…] comprehensive glycopeptide fragments than the conventional hcd-ms/ms spectra reported in ngag (supplementary fig. ). our search engine pglyco 2.0 showed better performance than the search engine gpquest used in ngag: pglyco 2.0 identified 97% more glycopeptide spectra than gpquest in the analysis of the same ms/ms data from ngag under the same peptide fdr (supplementary fig.  and methods). […]

[…] assignment of glycopeptides to tandem spectra and reduces the size of search space, thus improving the performance of the data mining process. this classification tactic has been incorporated into gpquest. together with a refined decoy and scoring algorithm, gpquest has been further improved to identify site-specific n- and o-glycosylation in the hcd ms/ms spectra of intact glycopeptides., […]
