Biosilica formation in diatoms: Characterization of native silaffin-2 and its role in silica morphogenesis
Open accessAbstract
The biological formation of inorganic materials with complex form (biominerals) is a widespread phenomenon in nature, yet the molecular mechanisms underlying biomineral morphogenesis are not well understood. Among the most fascinating examples of biomineral structures are the intricately patterned, silicified cell walls of diatoms, which contain tightly associated organic macromolecules. From diatom biosilica a highly polyanionic phosphoprotein, termed native silaffin-2 (natSil-2), was isolated that carries unconventional amino acid modifications. natSil-2 lacked intrinsic silica formation activity but was able to regulate the activities of the previously characterized silica-forming biomolecules natSil-1A and long-chain polyamines. Combining natSil-2 and natSil-1A (or long-chain polyamines) generated an organic matrix that mediated precipitation of porous silica within minutes after the addition of silicic acid. Remarkably, the precipitate displayed pore sizes in the range 100–1000 nm, which is characteristic for diatom biosilica nanopatterns.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
