Imaging DetailsThe original data (e.g., STAR files or micrograph metadata) are not available for this dataset. Therefore, the reported minimum and maximum defocus values (800 nm and 2500 nm, respectively) are based on standard cryo-EM data collection practices for similar resolution and instrumentation at the time of acquisition.
