Unusually Acidic Proteins in Biomineralization

摘要: Calcium carbonate biominerals are the most abundant mineral on surface of Earth. In eukaryotes, all biologically controlled calcium minerals associated with a minor organic matrix, which displays several essential functions: crystal nucleation, control shape, and growth inhibition. addition, matrix may be involved in enzymatic functions mediate cell–cell cell–matrix interactions. The is mixture proteins, glycoproteins, complex carbohydrates, proteoglycans, glycosaminoglycans and, sometimes, lipids. biochemical properties this have been studied numerous cases. One peculiarity shared by (if not all) matrices presence unusually acidic proteins; very often, these rich aspartic acid residues. nature their study unusual behaviour solution remain topics debate. chapter, we review our present knowledge proteins biomineralizations selected eukaryotic phyla.
