SugarQb (www.imba.oeaw.ac.at/sugarqb) is a freely available collection of computational tools for the automated identification of intact glycopeptides from high-resolution HCD MS/MS data-sets in the Proteome Discoverer environment. We report the migration of SugarQb to the latest and free version of Proteome Discoverer 2.1, and apply it to the analysis of PNGase F-resistant N-glycopeptides from mouse embryonic stem cells. The analysis of intact glycopeptides highlights unexpected technical limitations to PNGase F-dependent glycoproteomic workflows at the proteome level, and warrants a critical re-interpretation of seminal data-sets in the context of N-glycosylation-site prediction.

PNGases are crucial targets and valuable tools in analyzing asparagine-linked carbohydrate moieties (N-glycans) of glycoproteins. Activity tests of PNGases have been little improved since their discov...
Efficient separation and enrichment of low-abundance glycopeptides from complex biological samples is the key to the discovery of disease biomarkers. In this work, a new material was prepared by coati...
Hydrophilic interaction liquid chromatography (HILIC) is a useful tool in glycoproteomic analysis. Glutathione (GSH) is a well-known zwitterionic tripeptide with great hydrophilicity and biocompatibil...
Posttranslational N-glycosylation of food proteins plays a critical role in their structure and function. However, the N-glycoproteome of chicken egg yolk (CEY) has not been studied yet. Glycopeptides...
Label free quantification of shotgun proteomics data is a frequently used strategy, offering high dynamic range, sensitivity and the ability to compare a high number of samples without additional labe...
The hypothesis of this study is that many plasma proteins are altered in concentration and structure in preeclampsia and the elucidation of these alterations will add to the poorly underst...
The aim of the study is to investigate skeletal muscle proteome signature changes induced by exercise training in young men
Since the discovery of streptomycin in 1944, aminoglycosides retain a remarkable bactericidal activity vis-à-vis including aerobic gram-negative bacilli. Thus, their synergistic effect wi...
The aim of this study is to investigate the changes in glycopeptides of serum immunoglobulin G in patients with acute myocardial infarction and the relationships between its change and pro...
Drug resistant HIV strains often develop in patients who have taken anti-HIV drugs for an extended time. However, these drug resistant HIV strains do not always cause an increase in the l...
Strains of the genus Enterococcus that are resistant to the antibiotic VANCOMYCIN. The enterococci become resistant by acquiring plasmids carrying genes for VANCOMYCIN RESISTANCE.
The protein complement of an organism coded for by its genome.
The systematic study of the complete complement of proteins (PROTEOME) of organisms.
A method of chemical analysis based on the detection of characteristic radionuclides following a nuclear bombardment. It is also known as radioactivity analysis. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
Tuberculosis resistant to chemotherapy with two or more ANTITUBERCULAR AGENTS, including at least ISONIAZID and RIFAMPICIN. The problem of resistance is particularly troublesome in tuberculous OPPORTUNISTIC INFECTIONS associated with HIV INFECTIONS. It requires the use of second line drugs which are more toxic than the first line regimens. TB with isolates that have developed further resistance to at least three of the six classes of second line drugs is defined as EXTENSIVELY DRUG-RESISTANT TUBERCULOSIS.
