Design principles have been developed and tested to construct novel synthetic protein monomers that can self-assemble into large, open protein cages for potential use in vaccines and drug delivery.
Advances in the de novo design of coiled-coil proteins made by two different research groups proceeding by two different routes demonstrate that the range of protein nanostructures potentially available for various molecular machine systems is significantly larger than the range of such structures already exploited by natural selection.
By targeting the protein that attaches a type of immune cell called neutrophils to blood vessel walls where they cause serious tissues damage, the neutrophils are released and returned to the circulation to resume their normal functions.
A very large community of online gamers has consistently produced RNA designs that outperform the best design algorithms by a large margin. Can online gamers designing RNA, protein, and other molecules contribute to the development of atomically precise manufacturing?
A major advance in the computational design of proteins that bind tightly to specific small molecules will facilitate several technologies, possibly including the development of atomically precise manufacturing.
A porous metal-organic framework ‘host’ soaks up molecular ‘guests’ to form a crystalline complex, the structure of which can be determined by X-ray crystallography, providing atomic-resolution structures of minute amounts of guest molecules, and perhaps eventually other nanostructures.
Five proteins were designed from scratch and found to fold into stable proteins as designed, proving the ability to provide ideal, robust building blocks for artificial protein structures.
Tryptophan residues introduced at various positions in a protein chain identify folding intermediates that are too short-lived to be structurally characterized otherwise.
The Foldit approach to protein structure determination and protein design has proved its worth with the solution by citizen scientists in three weeks of an important protein structure that had stumped scientists working on the problem for more than a decade.
Progress in computational modeling of protein structures and in designing protein interfaces that bind in a desired geometrical orientation prepare the way for designing protein components of molecular machine systems.
