Our work is the first study to provide structures of several tRNAs before and after the introduction of modifications at specific sites. In detail, we analyzed 4 human tRNA species to decipher structural and stability effects induced by the installation of Ψ at single or multiple sites.

We used single particle cryo-EM to directly visualize several human tRNAs and analyze the effects of individual tRNA modifications. To our knowledge, the work presents interpretable maps of the smallest asymmetric particles analyzed by single-particle cryo-EM so far.

- identifies crucial contacts; very useful for selecting mutagenesis targets

- fixes model geometry. In cryo-EM, stereochemistry is usually the best priors you have!

- helps predicting models of weak complexes that AlphaFold3 cannot

Our findings emphasize how we use PDB models. It is critical to understand that PDB models are just that, models. They do not fully explain the underlying experimental data, have nuances in how they are representing the data, and as we show, can vary in how well the underlying data is explained.
