Characterization of lead-phytochelatin complexes by nano-electrospray ionization mass spectrometry
Frontiers in Microbiology, 2012 The role of phytochelatins (PCn, metal-binding oligopeptides with the general structure (γGlu - Cys)n - Gly (n = 2- 11)) in metal detoxification is assumed to be based on immobilization of metals, which prevents binding of metals to important ...

Switching Spike Plasticity Shapes ACE2 Engagement Across SARS‐CoV‐2 Variants
Advanced Science, EarlyView.Conformational plasticity governs SARS‐CoV‐2 spike function and ACE2 recognition. Using high‐speed AFM and single‐molecule force spectroscopy, we analyzed the ancestral spike and nine variants, revealing progressive rigidification from Delta, variable plasticity in Omicron sublineages, and JN.1 compaction.

Advanced Science, EarlyView.A liquid‐phase ion trap (LPIT) coupled with ESI‐MS enables rapid, high‐fidelity de novo sequencing of long oligonucleotides in ∼30 min. By applying an electric field to dissociate metal adducts in solution, LPIT delivers clean spectra, superior mass accuracy, and full sequence coverage, surpassing MALDI‐TOF and LC‐MS.

An Organic Chemist’s Guide to Electrospray Mass Spectrometric Structure Elucidation
Molecules, 2019 Tandem mass spectrometry is an important tool for structure elucidation of natural and synthetic organic products. Fragmentation of odd electron ions (OE+) generated by electron ionization (EI) was extensively studied in the last few decades, however ...

Advanced Science, EarlyView.AM symbiosis induces GhWAK13 to promote fungal colonization. GhNTF3 negatively regulates symbiosis by promoting SA biosynthesis. GhWAK13 sequesters GhNTF3 at the membrane, limiting its nuclear translocation and relieving SA‐mediated suppression. Under Verticillium stress, GhNTF3 enters the nucleus and interacts with GhJAZ6 to activate SA signaling ...
