Proteomics applications performed on the popular benchtop Q Exactive Orbitrap mass spectrometer have so far relied exclusively on higher collision-energy dissociation (HCD) fragmentation for peptide sequencing. While this fragmentation technique is applicable to a wide range of biological questions, it also has limitations, and all questions cannot be addressed equally well. Here, we demonstrate that the fragmentation capabilities of the Q Exactive mass spectrometer can be extended with ultravio ...[more]

Light-induced orthogonal fragmentation of crosslinked peptides

Project description:Crosslinking mass spectrometry provides pivotal information on the structure and interaction of proteins. MS-cleavable crosslinkers are regarded as a cornerstone for the analysis of complex mixtures. Yet they fragment under similar conditions as peptides, leading to mixed fragmentation spectra of the crosslinker and peptide. This hampers selecting individual peptides for their independent identification. Here we introduce orthogonal cleavage, using ultraviolet photodissociation (UVPD) to increase crosslinker over peptide fragmentation. We designed and synthesized a crosslinker that can be cleaved at 213 nm in a commercial mass spectrometer configuration. In an analysis of crosslinked E. coli lysate, the crosslinker-to-peptide fragment intensity ratio increases from nearly 1 for a conventionally cleavable crosslinker to 5 for the UVPD cleavable crosslinker. This largely increased the sensitivity of selecting the individual peptides for MS3, even more so with an improved doublet detection algorithm.

Ultraviolet Photodissociation of ESI and MALDI generated protein ions on a Q-Exactive mass spectrometer

Project description:UVPD was implemented on an Orbitrap Q-Exactive plus equipped with a ESI/EP-MALDI. UVPD of MALDI generated ions was benchmarked against MALDI-ISD, MALDI-HCD and ESI-UVPD. MALDI UVPD outperformed MALDI HCD and ISD efficiently sequencing small proteins ions.

Ultraviolet Photodissociation of tryptic peptide backbones at 213 nm

Project description:We analyzed the backbone fragmentation behavior of tryptic peptides of a four protein mixture and of E. coli lysate subjected to Ultraviolet Photodissociation (UVPD) at 213 nm on a commercially available UVPD-equipped tribrid mass spectrometer. We obtained 15,178 high-confidence peptide-spectrum matches by additionally recording a reference beam-type collision-induced dissociation (HCD) spectrum of each precursor. Type a, b and y ions were most prominent in UVPD spectra and median sequence coverage ranged from 5.8% (at 5 ms laser excitation time) to 45.0% (at 100 ms). Overall sequence fragment intensity remained relatively low (median: 0.4% (5 ms) to 16.8% (100 ms) of total intensity) and remaining precursor intensity high. Sequence coverage and sequence fragment intensity ratio correlated with precursor charge density, suggesting that UVPD at 213 nm may suffer from newly formed fragments sticking together due to non-covalent interactions. UVPD fragmentation efficiency therefore might benefit from supplemental activation, as was shown for ETD. Aromatic amino acids, most prominently tryptophan, facilitated UVPD. This points at aromatic tags as possible enhancers of UVPD. Data are available via ProteomeXchange and on spectrumviewer.org/db/UVPD_213nm_trypPep

Integrative proteomic and phosphoproteomic analyses revealed the regulation mechanism of Clematis terniflora DC. response to UV-B stress

Project description:Clematis terniflora DC. is used as traditional herb medicine since ancient China. The active substances in C.terniflora have been confirmed to be effective in treating disease like prostatitis. The UV light radiation is a common environmental factor that damage the plants and has an influence on the primary metabolism and secondary metabolism. Previous researches have shown that ultraviolet B (UV-B) radiation followed by dark stress acting on C.terniflora leaves，resulting in the accumulation of secondary metabolites. An in-depth understanding of how C.terniflora leaves respond to UV-B stress is crucial for improving medicinal plants value. Here, we conducted label-free proteomic and phosphoproteomic to explore the protein changes under UV-B and UV-B combined with dark treatment, respectively. A total of 2839 proteins and 1638 phosphorylated proteins were identified. Integrative omics revealed the photosynthetic system and carbohydrate balance were modulated in both stresses. The phosphoproteomic data indicated that, mitogen-activated protein kinase signaling pathway was triggered, meanwhile, the abundance of phosphorylated proteins related to the osmotic stress were increased under UV-B stress. Differential abundant phosphoproteins from UV-B followed by dark treatment were mainly enriched in response to stimulus including calcium-mediated proteins. This study dissects the impact of UV-B stress on C.terniflora and the plant molecular resistant mechanisms through proteomic and phosphoproteomic in a new sight.

TEF-seq/NET-seq applied to factors Rpb3, Paf1, Spt6, Spt16, Cet1, Pcf11, Ssu72, Set2

Project description:Here we adapt native elongating transcript sequencing (NET-seq) to develop transcription elongation factor associated nascent elongating transcript sequencing (TEF-seq). In this the RNA polymerase II (Pol2) transcription elongation complex (TEC) is immunoprecipitated via associated transcription elongation factors (TEFs). Sequencing from the 3' end of the Pol2-associated nascent transcript shows the position of the final incorporated nucleotide giving strand-specific, single nucleotide resolution maps of the level of TEF association with Pol2 during transcription.

Expression data from U87MG cells expressing EGFRvIII

Project description:EGFRvIII is the most common deletion mutant of EGFR in human cancer and its levels are highly correlated with poor prognosis in GBM. The deletion of exons 2-7 removes most of the extracellular ligand binding domain, so it is unable to bind EGF or other EGFR-binding ligands. Nevertheless, the mutant receptor is constitutively phosphorylated, and is capable of activating downstream signaling pathways at a low level. To comprehensively identify the downstream signaling consequences of the EGFRvIII, we incorporated phosphoproteomic, transcription profiling and DNase-Seq data from U87MG glioblastoma cells expressing titrated levels of this mutant receptor. Total RNA were extracted from U87MG cells engineered to expressed different levels of EGFRvIII: medium (U87M; 1.5 million copies of EGFRvIII receptor per cell), high (U87H; 2 million copies per cell), super-high (U87SH; 2.5 million copies per cell), and kinase-dead EGFRvIII (U87DK; 2 million copies of kinase dead EGFRvIII per cell). RNA was hybridized to Affymetrix microarrays.
