Dynamic changes in the secondary structure content of proteins can provide valuable insights into protein function or dysfunction. Predicting these dynamic changes is still a significant challenge but is of paramount importance for basic research as well as drug development. Here, we present a machine learning-based model that predicts the secondary structure content of proteins based on their un assigned1H,15N-HSQC NMR spectra with an RMSE of 0.11 for -helix, 0.08 for {beta}-sheet and 0.12 for random coil content. Our model has been implemented into an easy-to-use and publicly available web service that estimates secondary structure content based on a provided peak list. Furthermore, a Python version is provided, ready to be integrated into Brukers TopSpin software or own scripts.

Matching journals

The top 8 journals account for 50% of the predicted probability mass.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
