Structures from the Mesophase: MicroED Targets Crystals Extracted from LCP

摘要

The determination of protein structures from nanocrystals grown in lipidic cubic phase (LCP) is a promising crystallographic approach. In this issue of Structure, Zhu et al. (2020) extract crystals from the dense matrix of monoolein LCP for interrogation by micro electron diffraction (MicroED) and yield a 2 angstrom structure of Proteinase K.
