Nature’s Microscopic Masonry: The First Steps in How Thin Protein Sheets Form Polyhedral Shells

Scientists have for the first time viewed how bacterial proteins self-assemble into thin sheets and begin to form the walls of the outer shell for nano-sized polyhedral compartments that function as specialized factories. The research provides new clues for scientists seeking to use these 3-D structures as “nanoreactors” to selectively suck in toxins or churn out desired products.
