Protein Dynamics at Different Timescales Unlock Access to Hidden Post-Translational Modification Sites
Post-translational modifications (PTMs) alter the proteome in response to intra- and extracellular signals, providing fundamental information processing in development, homeostasis and disease. Here, ...

Structures of protein folding intermediates on the ribosome
The ribosome biases the conformations sampled by nascent polypeptide chains along folding pathways towards biologically active states. A hallmark of the co-translational folding (coTF) of many protein...

Long-range electrostatic forces govern how proteins fold on the ribosome
Protein biosynthesis and folding are tightly intertwined processes regulated by the ribosome and auxiliary factors. Nascent proteins can begin to fold on their parent ribosome but formation of the nat...

The ribosome lowers the entropic penalty of protein folding
Nature, Published online: 07 August 2024; doi:10.1038/s41586-024-07784-4 Structures of the growing peptide chain on and off the ribosome reveal that the ribosome destabilizes the unfolded nascent chain, promoting the formation of partially folded intermediate states.

Rational design of 19F NMR labelling sites to probe protein structure and interactions
Proteins are investigated in increasingly more complex biological systems, where 19F NMR is proving highly advantageous due to its high gyromagnetic ratio and background-free spectra. Its application ...
