The recent years have witnessed a dramatic development of computational methods for the prediction of protein structures, and the advent of artificial intelligence has dramatically changed the tools used by scientists for the prediction of protein structures and of protein-protein complexes. This has also marked a dramatic advancement in the de novo design of proteins, enabling the engineering of new nanomaterials. I will present the most recent breakthroughs in experimental protein structure analysis and computational protein structure predictions, with a focus on drug discovery and on the development of protein nanomaterials.
