In a recent study posted to the bioRxiv* preprint server, researchers discovered that the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is susceptible to cleavage at ...

Unbound proteins in a cell break up protein-DNA bonds as they compete for the single-binding site, new research has found. The verdict is in: too many single, flirty proteins can break up a strong ...

Temporary protein-protein bonds are essential for processes including enzymatic reactions, antibody binding, and response to medication. Being able to accurately characterize these bonds is important ...

Disulfide bonds play a pivotal role in the folding and stability of many bacterial proteins, influencing not only their tertiary structure but also their biological activity. In bacteria, the ...

Protein low-complexity domains (LCDs) stack together to form dynamic liquid droplets within the cell; alas, some pathogenic mutations in these regions encourage aggregation beyond this temporary ...

Water has a split personality. When it’s flowing freely in a glass or a river, it’s the easygoing liquid we all know. But ...

An artist’s conception shows a fanciful view of organosilicon-based life. (Lei Chen and Yan Liang / BeautyOfScience.com for Caltech) Using directed evolution, researchers say they’ve “bred” protein ...

Silicon is the second most abundant element in Earth’s crust after oxygen, but carbon-silicon bonds are unheard of in nature: Neither biological organosilicon compounds nor biosynthetic pathways to ...

Protein hydrolysates are produced by breaking down proteins into short protein fragments (peptides) and amino acids. They are ...

The verdict is in: too many single, flirty proteins can break up a strong relationship. A new interdisciplinary Northwestern University study reports that the important protein-DNA bond can be broken ...
