We propose that the forward and reverse halves of a flash-induced protein-protein electron transfer (ET) photocycle should exhibit differential responses to dynamic interconversion of configurations ...

A mechanistic understanding of the cell requires the structural characterization of the thousands of its constituent biological assemblies 1. So far, conventional approaches have provided a valuable ...

To function correctly, cellular proteins depend not only on their complex tertiary and quaternary structures, but also on their proximity to and interactions with other molecules participating in the ...

Scientists report two new cryo-EM structures representing the pre- and postfusion conformations of the full-length SARS-CoV-2 spike (S) protein, an essential viral component responsible for host cell ...

A USC-led international team of scientists has found the precise shape of a key player in human metabolism, which could lead the way to better treatments for obesity and other metabolic disease. For ...
