Breaking Cryo-EM Resolution Barriers to Facilitate Drug Discovery Using cryo-EM we were able to capture images of glutamate dehydrogenase (GDH), an enzyme found in cells, at a resolution of 1.8 angstroms, a level of detail at which the structure of the central parts of the enzyme could be visualized in atomic detail. We also imaged two small proteins in…
2.3 Å Resolution Cryo-EM Structure of Human p97 and Mechanism of Allosteric Inhibition The protein p97 is an AAA adenosine triphosphatase (ATPase) that uses energy from ATP hydrolysis to regulate substrates involved in intracellular protein quality control. Its role in this central process makes it a target for cancer chemotherapy. We used cryo-electron microscopy to determine high-resolution structures for…
