The software tool ProteinMPNN (Message Passing Neural Network) from Baker Lab can predict from a given 3D protein structure possible amino acid sequences that would fold into the given structure, in this way effectively reversing what AlphaFold from DeepMind or ESMFold from Meta can do. So the approach allows to design proteins. With a DNA/RNA printer as the BioXp from TelesisBio or the Syntax system from DNAScript it is possible to directly output the desired protein or a virus that generates the protein in a cell when injected into the body.

The source code is available on GitHub and has also already been integrated into a Hugging Face space. See also here.
