PDB The Protein Data Bank (PDB) is a database of 3D structural data of large biological molecules, such as proteins and nucleic acids. These data are gathered using experimental methods such as X-ray crystallography, NMR spectroscopy, or cryo-electron microscopy AlphaFoldDB AlphaFoldDB is a data...
5 Molecular-level design of engineered protein materials Similar to peptide-engineered materials, ECM-mimetic proteins are also created through rational design, with modular peptide units fused together to form a multi-functional protein chain. While peptide materials are typically produced using synthetic...
Photolabeling of intracellular molecules is an invaluable approach to study multiple cellular processes. Here, the authors report on the near-infrared to far-red photoconversion in the miRFP family of fluorescent proteins, which enables photolabeling entirely performed in the near-infrared range. France...
Using cryo-electron microscopy, the structures of human UCP1 in the nucleotide-free state, the DNP activator-bound state, and the inhibitory ATP-bound state are resolved, providing details of how purine nucleotides inhibit UCP1. Yunlu Kang ...
Silks are protein-based fibers made by arthropods for a variety of task-specific applications. Silk fibers are typically composite materials formed of silk protein and other associated molecules such as glycoproteins and lipids [40], [41], [42], [43], [44]. 1.2.1. Silkworm silk Of all na...

Escherichia coli, one of the most efficient expression hosts for recombinant proteins (RPs), is widely used in chemical, medical, food and other industries. However, conventional expression strains are unable to effectively express proteins with complex
This Review provides an overview of physiological barriers to the oral delivery of biologics and highlights the advances made in materials across various length scales, from small molecules to macroscopic devices. This Review also describes the current status of materials for oral delivery of protein ...
aThrough a meta-analysis of the experimental literature we find an appreciable fraction (indicated by the red shaded region of each subplot) of protein molecules bypass chaperones in vitro even though they are not folded (i.e., have not regained activity), and take a minimum of days or long...
However, characterizing this activity at a molecular level is difficult due to its complexity: First, the activation of these proteins is largely connected to their ambivalent folding properties, since they are stable both in water and lipidic media, but only the structure of the inactive, water-...
