[…] ink 2 is ~40 times faster than pLink, with a friendly graphical interface and some further improvements in accuracy. pLink 2 was officially released on January 1, 2018 and can be downloaded at 1 Fig. 2 Fig. 3In this paper, we present a step-by-step disulfide mapping protocol using the method we developed in 2015. As shown in Fig. , this protocol contains […]


Combining Chemical Cross linking and Mass Spectrometry of Intact Protein Complexes to Study the Architecture of Multi subunit Protein Assemblies

PMCID: 5755487
PMID: 29286378
DOI: 10.3791/56747

[…] e searching NOTE: There is different software available for database searching. MaxQuant, for instance, is freely available. Convert .raw-files into .mgf-files using a pXtract conversion tool ( database search using typical search parameters: Database, swissprot; peptide mass tolerance, 10 ppm; fragment mass tolerance, 0.5 Da; enzyme, trypsin; missed c […]


O GlcNAcylation of SIRT1 enhances its deacetylase activity and promotes cytoprotection under stress

[…] ypically 2500 V in the nano-LC (liquid chromatography) ESI MS/MS mode. For LTQ Orbitrap XL™ ETD mass spectrometer analysis, the ion source voltage is set to 1500 V. MS/MS data were searched using the pFind program for O-GlcNAcylated peptides, and the spectra were annotated using pLabel–. […]


Structure based biophysical characterization of the PROPPIN Atg18 shows Atg18 oligomerization upon membrane binding

Sci Rep
PMCID: 5656675
PMID: 29070817

[…] d peptides. Internal calibration of the orbitrap was performed using the lock mass option (lock mass: m/z 445.120025).Raw data files were converted into mgf format using pXtract software tool ( Potential cross-links were then identified by database searching against a reduced database containing Atg18 using pLink search engine. Search parameters were: fragment […]


pGlyco 2.0 enables precision N glycoproteomics with comprehensive quality control and one step mass spectrometry for intact glycopeptide identification

Nat Commun
PMCID: 5585273
PMID: 28874712
DOI: 10.1038/s41467-017-00535-2

[…] he fine-scoring step.The second step is fine-scoring, which was a scoring scheme for a GSM. For each valid glycan candidate after coarse scoring, the corresponding candidate peptides were searched by pFind based only on the peptide backbone mass, . pFind has been compiled into a static link library that could be called automatically by pGlyco 2.0 without installing pFind Studio. After peptide sear […]


Proteome wide acetylation dynamics in human cells

Sci Rep
PMCID: 5579049

[…] with the Orbitrap as the detector. Dynamic exclusion was set to 60 seconds. HCD collision energy was set to 27, AGC target to 5e4 and maximum injection time to 200 msec.MS raw files were analyzed by pFind. MS/MS spectra were searched against the Human UniProt FASTA database [9606]. The modifications considered included acetylation and oxidation, and the fixed modification was carbamidomethylation […]
