Scaffolds with optimized quaternary symmetry for de novo cryoEM structure determination of small RNAs

Scaffolds with optimized quaternary symmetry for de novo cryoEM structure determination of small RNAs

Engineered RNA domains that can adopt two- and fourfold symmetry are shown to be effective scaffolds for structure determination for RNAs otherwise too small for cryoEM.

Here we describe cryoEM sample preparation and evaluation, grid preparation, cryoEM data collection and analysis, map interpretation and model building. CryoEM reporting follows recently published co… [+16232 chars]
