Noncovalent PEGylation via Lectin–Glycopolymer Interactions [PDF]

Biomacromolecules, 2016
La PEGylation, la modification covalente des protéines avec le polyéthylène glycol, est une technique abondamment utilisée pour améliorer la pharmacocinétique des protéines thérapeutiques. L'inconvénient de cette méthodologie est que le PEG fixé de manière covalente peut entraver l'activité biologique (par exemple, une capacité réduite de liaison aux ...

Small Molecules, Non-Covalent Interactions, and Confinement

Molecules, 2020
This review gives an overview of current trends in the investigation of small guest molecules, confined in neat and functionalized mesoporous silica materials by a combination of solid-state NMR and relaxometry with other physico-chemical techniques. The

Thermoring basis for the proton-driven heat activation of a cation-selective channel in myriapods

Scientific Reports
Thermo-gated ion channels undergo significant time-dependent structural rearrangements for activation. Although the tertiary noncovalent interaction networks can be constrained as thermorings to explain specific temperature thresholds and sensitivity ...

Noncovalent Interactions in Catalysis [PDF]

, 2019
Noncovalent interactions often provide the spine of biomolecular and material structures, and can therefore play a key role in biological and catalytic processes. Selectivity in chemical reactions, particularly in catalytic processes, is often an orchestral action of various noncovalent interactions occurring in intermediates and transition states ...
