A Perfectly Periodic Three-Dimensional Protein/Silica Mesoporous Structure Produced by an Organism

The discovery of perfectly ordered 3D mesoporous protein/silica structure in the axial filament of the marine sponge Monorhaphis chuni is reported. The structure belongs to body‐centered tetragonal symmetry system (a = 9.88 nm, c = 10.83 nm) and comprises interconnecting lattices of protein and sili...

Summary:The discovery of perfectly ordered 3D mesoporous protein/silica structure in the axial filament of the marine sponge Monorhaphis chuni is reported. The structure belongs to body‐centered tetragonal symmetry system (a = 9.88 nm, c = 10.83 nm) and comprises interconnecting lattices of protein and silica, templated by the self‐assembled, enzymatically active protein‐silicatein, whose primary function is the precipitation of silica.
