System of forest insect pheromone communication: stability of «information» molecules to environmental factors [PDF]

Сибирский лесной журнал, 2016
Features of external environmental factors (such as electromagnetic radiation in certain spectral bands) influencing pheromone molecules, which are carriers of information for forest insects in the search of the opposite sex, were examined.

Decoding elegant interplay among different stereo-electronic effects due to the ancient prolyl-4-hydroxylation stabilizing collagenous helicity

iScience
Summary: Prolyl-4-hydroxylation is an ancient evolutionarily conserved post-translational modification (PTM) critical for both structural and regulatory functions in multicellular life forms. This PTM plays a pivotal role in stabilizing collagen’s triple

5,10,15,20-Tetra(4-pyridyl)-21H,23H-porphine as an effective corrosion inhibitor for N80 steel in 3.5% NaCl solution

International Journal of Electrochemical Science, 2014
The inhibition behavior of 5,10,15,20-Tetra(4-pyridyl)-21H,23H-porphine (T4PP) as an environmentbenign corrosion inhibitor for N80 steel was investigated in 3.5 wt.% NaCl solution by means of potentiodynamic polarization, AC impedance, and quantum ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Shallow-circuit variational quantum eigensolver based on symmetry-inspired Hilbert space partitioning for quantum chemical calculations

Physical Review Research, 2021
Development of resource-friendly quantum algorithms remains highly desirable for noisy intermediate-scale quantum computing. Based on the variational quantum eigensolver (VQE) with unitary coupled-cluster Ansatz, we demonstrate that partitioning of the ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.
