Abstract
X-ray crystallography is a powerful approach for understanding the structure and function of biological macromolecules but is largely limited to molecules that form high-quality crystals in the laboratory. Here we present the structure of protein crystals that form naturally in virally infected insects and boost the insecticidal activity of oral pathogens. By proposing a mode of action for these virulence factors based on enzymes degrading chitin by oxidation, our findings may guide their use as synergetic additives to common bioinsecticides. They also reveal that these proteins assemble into ultra-stable crystals stabilized by a 3D network of covalent bonds, a unique strategy for achieving efficient protein crystallization in the complex environment of the cell.
