Scientists are making a case for adjusting our understanding of how exactly genes first emerged. For a while, there’s been a consensus about the order in which the building-bloc ...

A novel protein cage system can control and visualize orientational changes in aromatic side chains upon ligand binding. By inducing coordinated molecular changes, this approach enables precise ...

NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) mission has detected amino acids in the largest asteroid sample ever collected in space, ...

There are 20 amino acids that make up proteins and all have the same basic structure, differing only in the R-group or side chain they have. Amino acids are in an equilibrium between two acids with ...

The team engineered special "pockets" within a protein cage structure called ferritin, surrounding these pockets with carefully arranged clusters of aromatic amino acids. When specific fluorescent ...
