Recovering protein conformations from single-particle cryo-EM data via indirect shape matching gradient flows
Summary
arXiv:2608.17759v1 Announce Type: new Abstract: Single-particle cryo-electron microscopy images a macromolecule as many noisy tomographic projections of its electrostatic potential. We reconstruct the protein backbone directly from such projections, as an atomic point cloud, without the intermediate step of reconstructing the 3D electrostatic potential map. We formulate this as an indirect shape matching problem: a point-cloud template of the backbone is deformed until its simulated projections agree with the data, with the structure observed only through the imaging operator.
Why It Matters
This Biotech development strengthens the region's biomanufacturing and life-sciences base. For Asia, it is a signal worth tracking: it shapes who supplies, who scales, and who sets the standard over the next five years.
