Cryo-EM of large, macromolecular assemblies has seen a significant increase in the numbers of high-resolution structures since the arrival of direct electron detectors. However, sub-nanometre resolution cryo-EM structures are rare compared with crystal structure depositions, particularly for relatively small particles (<400 kDa). Here we demonstrate the(More)
The potential for protein tectons to be used in nanotechnology is increasingly recognized, but the repertoire of stable proteins that assemble into defined shapes in response to an environmental trigger is limited. Peroxiredoxins (Prxs) are a protein family that shows an amazing array of supramolecular assemblies, making them attractive tectons. Human Prx3(More)
Peroxiredoxins (Prxs) are a ubiquitous class of thiol-dependent peroxidases that play an important role in the protection and response of cells to oxidative stress. The catalytic unit of typical 2-Cys Prxs are homodimers, which can self-associate to form complex assemblies that are hypothesized to have signaling and chaperone activity. Mitochondrial Prx3(More)
