The results revealed that the differences in arrival time distributions (ATDs) were inadequate to differentiate the isomers unambiguously. However, the ATD profiles of the product ions, generated by fragmenting the respective mass-selected <i>m</i>/<i>z</i> 201 precursor ions in the <i>Trap</i> region of the three-compartment traveling-wave ion guide of the Synapt G2 mass spectrometer, were distinctly different, enabling definitive differentiation of the isomers. An arrival-time peak for an ion of <i>m</i>/<i>z</i> 157 resulting from the loss of CO<sub>2</sub> from the respective precursors was common to all three mobilograms. However, only the profile recorded from the <i>para</i>-isomer exhibited a unique arrival-time peak for an ion of <i>m</i>/<i>z</i> 137, originating from an SO<sub>2</sub> loss. Such a peak corresponding to an SO<sub>2</sub> loss was absent in the ATD profiles of the <i>ortho</i>- and <i>meta</i>-isomers. Additionally, the mobilogram of the <i>meta</i>-isomer displayed a unique peak at 3.42 ms. Based on its product ion spectrum, this peak was attributed to the bisulfite anion (<i>m</i>/<i>z</i> 81; HSO<sub>3</sub>ˉ). Previously, this <i>meta</i>-isomer specific <i>m</i>/<i>z</i> 81 ion had been proposed to originate from a two-step process involving the intermediacy of an <i>m</i>/<i>z</i> 157 ion formed by CO<sub>2</sub> loss. However, our detailed tandem mass spectrometric experiments suggest that the <i>m</i>/<i>z</i> 81 is not a secondary product but rather an ion that originated from a direct elimination of a benzyne derivative from the <i>m</i>/<i>z</i> 201 precursor ion.</p>","PeriodicalId":16178,"journal":{"name":"Journal of Mass Spectrometry","volume":"59 8","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141579987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Other PCs were noticed in both types of roots, uncontaminated and cadmium-contaminated, but the intensities were higher in the former samples. Moreover, long-time exposure to cadmium stimulated the formation of some of these PCs and their cadmium complexes.

Borotto","doi":"10.1002/jms.5064","DOIUrl":"10.1002/jms.5064","url":null,"abstract":"<p>Mass spectrometry-based approaches to assess protein conformation have become widely utilized due to their sensitivity, low sample requirements, and broad applicability to proteins regardless of size and environment. Their wide applicability and sensitivity also make these techniques suitable for the analysis of complex mixtures of proteins, and thus, they have been applied at the cell and even the simple organism levels. These works are impressive, but they predominately employ “bottom-up” workflows and require proteolytic digestion prior to analysis. Once digested, it is not possible to distinguish the proteoform from which any single peptide is derived and therefore, one cannot associate distal—in primary structure—concurrent post-translational modifications (PTMs) or covalent labels, as they would be found on separate peptides. Thus, analyses via bottom-up proteomics report the average PTM status and higher-order structure (HOS) of all existing proteoforms. Second, these works predominately employ promiscuous reagents to probe protein HOS. While this does lead to improved conformational resolution, the formation of many products can divide the signal associated with low-copy number proteins below signal-to-noise thresholds and complicate the bioinformatic analysis of these already challenging systems. In this perspective, I further detail these limitations and discuss the positives and negatives of top-down proteomics as an alternative.</p>","PeriodicalId":16178,"journal":{"name":"Journal of Mass Spectrometry","volume":"59 7","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141317544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the intensity fading MALDI-TOF mass spectrometry (IF-MALDI-MS) method with improved reproducibility was implemented to investigate the binding interactions between saponins from <i>Panax notoginseng</i> and lysozyme. The benchmark IF-MALDI-MS experiment was established using <i>N</i>,<i>N</i>′,<i>N</i>″-triacetylchitotriose-lysozyme as a model system. The reproducibility of ion intensities in IF-MALDI-MS was improved by scanning the whole sample deposition with a focused laser beam. The relative standard deviation (RSD) of deposition scanning IF-MALDI-MS is 5.7%. Similar decay trends of the relative intensities of notoginseng saponins against increasing amounts of lysozyme were observed for all six notoginseng saponins. The half-maximal fading concentration (FC<sub>50</sub>) was calculated to quantitatively characterize the binding affinity of each ligand based on the decay curve. According to the FC<sub>50</sub> values obtained, the binding affinities of the six notoginseng saponins were evaluated in the following order: notoginsenoside S &gt; notoginsenoside Fc &gt; ginsenoside Rb1 &gt; ginsenoside Rd &gt; notoginsenoside Ft1 &gt; ginsenoside Rg1.
