O-GlcNAcylation inhibits the oligomerization of alpha-synuclein by declining intermolecular hydrogen bonds through a steric effect [PDF]
Physical Biology, 2020 Toxic abnormal aggregation of α-synuclein (α-Syn) is a feature of Parkinson’s disease. Several biochemical and biophysical studies have demonstrated that many post-translational modifications (PTM) of α-Syn could distinctly alleviate its oligomerization ...

Steric effect of intermediates induces formation of three-dimensional covalent organic frameworks [PDF]
Nature CommunicationsConstructing three-dimensional covalent organic frameworks (3D COFs) remains a significant challenge compared to other areas of reticular chemistry. Most existing methods for constructing 3D COFs emphasize the necessity of at least one precursor being ...
