Title: Calcium-Induced Molecular Rearrangement of Peptide Folds Enables Biomineralization of Vaterite Calcium Carbonate

15.03.2018 | Susan Hjort Skyum

Calcium carbonate (CaCO3) is the most abundant mineral on earth and plays an important role for life. CaCO3 is a key component of marine animals such as mollusk, mussels and sponges. The biogenesis of CaCO3-based hard tissue is tightly controlled by proteins, which exert control over the nucleation and growth of the specific phase of CaCO3, calcite, aragonite and vaterite. The latter phase occurs almost exclusively as a biomineral and has applications in drug delivery, implant design and surface coating. In this article we used surface spectroscopy and molecular dynamics simulations to determine, at the molecular level, how proteins control the formation of vaterite phase CaCO3.
