2D template matching with high-resolution priors improves cryo-EM alignment and reconstruction of a previously intractable ~43 kDa protein kinase, enhancing its ligand-binding site density.
- Why it matters: Small proteins and complexes have been difficult to resolve by single-particle cryo-EM, limiting near-native structural studies and drug-relevant targets below 100 kDa.
- What they did: The authors use high-resolution structures as priors combined with 2D template matching to align and reconstruct small macromolecular complexes, including a ~43 kDa protein kinase.
- The result: Their theoretical analysis predicts the approach can extend single-particle cryo-EM to drug-binding complexes well below 50 kDa.
