Out now in #NAR! 🧬 I mapped the evolution of the ribosomal exit tunnel through the "eyes" of the nascent chain using MD simulations. How do the tunnel geometry, lateral branching, and chemical landscape change across 64 distinct ribosomes from the 3 domains of life? academic.oup.com/nar/article/...

Evolution of the ribosomal exit tunnel through the eyes of the nascent chain
Abstract. The exit tunnel is a universally conserved feature of the ribosome that directs the nascent polypeptide into the cellular environment and is invo

Now in Nature SMB: how do proteins fold while still being made? We solved all-atom structures of two ribosome-tethered folding intermediates—invisible to cryo-EM, seen only by ¹⁹F NMR. Thank you @julianstreit.bsky.social, John Christodoulou & co-authors! nature.com/articles/s41594-026-01814-7

Evolution of the ribosomal exit tunnel through the eyes of the nascent chain
The ribosomal exit tunnel is a universally conserved feature of the large subunit that directs the nascent polypeptide chain into the cellular environment and is involved in co-translational folding, ...

In press!! NMR & MD simulations reveal how non-native contacts stabilise a key transient intermediate in the lysozyme amyloid cascade. Well done Minkoo and all!! @phar.cam.ac.uk For CMD ❤️ advanced.onlinelibrary.wiley.com/doi/10.1002/...

Amyloid Forming Human Lysozyme Intermediates are Stabilized by Non‐Native Amide‐π Interactions
Mutational variants of human lysozyme cause fatal systemic amyloidosis by depositing kilograms of protein in the viscera of patients. Central to this process is a partially unfolded protein intermedi....
