Cryo-EM Facility at SOLARIS — A Highlight Review of Complex Biological Assemblies
Main Article Content
Abstract
Cryo-electron microscopy has emerged as a transformative technique in structural biology, enabling the high-resolution structural determination of large and heterogeneous biological assemblies. This review highlights recent advances in understanding the structural and functional diversity of protein cages, ribonucleic acid molecules and complexes, as well as enzyme complexes, as revealed by cryo-electron microscopy. We discuss how cryo-electron microscopy provides unique insights into the architecture, dynamics, and mechanisms of action of these essential biological components.
