The first cut is the deepest: Cleavable signal peptides direct thousands of different nascent proteins to the endoplasmic reticulum. Oddly, SPs are all different and nevertheless cleaved with exquisite specificity. Our new cryo-EM structures + MD solve this paradox: www.nature.com/articles/s41...

Structural basis of signal peptide recognition by the signal peptidase complex - Nature Communications

Signal peptides are highly variable, yet the signal peptidase complex processes them with remarkable specificity. Here, authors combine cryo-EM, molecular dynamics simulations and modeling to reveal a...

One of the last works from my PhD is finally out! We delved deep into water dynamics as a function of pH, in a series of high-resolution structures. The manuscript is now online at @pnas.org! If you're into high-res biochemical insights, I promise its worth the read! #cryoEM #biochemistry #SPA

A project that would never leave my mind during my PhD is finally out! We used #cryo-em #spa #md to see how the solvation layer of a protein is affected during acidification! Really cool insights and a truly fundamental work, congrats to all involved! www.biorxiv.org/content/10.1...

Having now worked myself on tomo data collection and analysis makes me appreciate the enormity of this work even more! Amazing stuff...
