- Atomic Resolution Cryo-EM Structure of B-galactosidase
- Cryo-EM, Methods
- Atomic Resolution Cryo-EM Structure of B-galactosidase We report methods to account for radiation damage and local changes in defocus and image drift, enabling visualization of atomic resolution features in a cryo-EM density map of inhibitor-bound b-galactosidase, and measuring of local flexibility of the bound inhibitor using constrained molecular dynamics simulations.

- Protein Secondary Structure Determination by Constrained Single-Particle Cryo-Electron Tomography We propose a hybrid strategy, constrained single-particle tomography (CSPT), that combines the advantages of cryo-electron tomography and subvolume averaging with those of traditional single-particle reconstruction and projection matching refinement. Its key components are the effective manipulation of images from tomographic tilt series to successfully extract high-resolution information and correct for…
