Recovering protein conformations from single-particle cryo-EM data via indirect shape matching gradient flows
Erik Jansson, Jonathan Krook, Ozan Öktem +1
Single-particle cryo-electron microscopy images a macromolecule as many noisy tomographic projections of its electrostatic potential. We reconstruct the protein backbone directly f…

Protein Graph Neural Networks for Heterogeneous Cryo-EM Reconstruction
Jonathan Krook, Axel Janson, Joakim Andén +2
We present a geometry-aware method for heterogeneous single-particle cryogenic electron microscopy (cryo-EM) reconstruction that predicts atomic backbone conformations. To incorpor…

Geometric shape matching for recovering protein conformations from single-particle Cryo-EM data
Erik Jansson, Jonathan Krook, Klas Modin +1
We address recovery of the three-dimensional backbone structure of single polypeptide proteins from single-particle cryo-electron microscopy (Cryo-SPA) data. Cryo-SPA produces nois…
