Determining structures in a native environment using single-particle cryoelectron microscopy images
The Innovation, 2021 Cryo-electron tomography is a powerful tool for structure determination in the native environment. However, this method requires the acquisition of tilt series, which is time-consuming and severely slows structure determination. By treating the densities
