Single amino acid variation identification in high resolution tandem mass spectrometry data in bottom up proteomics

Two new supramolecular halometalate hybrid complexes, (H2bpen){[MCl5](I2)} (M = Sb(III) (1) and Bi(III) (2); bpen – 1,2-Bis(4-pyridyl)ethylene, have been prepared. Despite very close similarity of the nature of cations, they reveal significant structural difference from the (H2bpe){[MCl5](I2)} (bpe – 1,2-bis(4-pyridil)ethane) reported earlier. We discuss these features, along with thermal stability, optical properties as well as Raman spectra ...

DFT-guided charge-state engineering of gold clusters for levodopa recognition: fundamental principles for drug delivery applications

Obijiofor O., Новиков А. С., New Journal of Chemistry 2026 Vol. 50 No. 23 P. 9749–9768

Rational design of gold-based nanocarriers for neurotherapeutics requires atomic-scale understanding of drug-material interactions. Density functional theory calculations were performed to investigate levodopa (L-DOPA) adsorption on small gold clusters (Au2–Au4) with cationic, neutral, and anionic charges, with additional validation on a larger Au10 cluster using multiple low-energy isomers. Binding free energies (ΔGbind), charge transfer, and electronic descriptors ...

The first step in the analysis of protein tandem mass spectrometry data typically involves searching the observed spectra against a protein database. During database search, the search engine must digest the proteins in the database into peptides, subject to digestion rules that are under user control. The choice of these digestion parameters, as well as ...

Spectrum annotation is a challenging task due to the presence of unexpected peptide fragmentation ions as well as the inaccuracy of the detectors of the spectrometers. We present a deep convolutional neural network, called Slider, which learns an optimal feature extraction in its kernels for scoring mass spectrometry (MS)/MS spectra to increase the number of ...
