IN the initial stages of the biomineralization of abalone shells, a primer layer of oriented calcite crystals grows on a nucleating protein sheet1,2. The deposition of this primer is followed by an abrupt transition to c-axis-oriented crystals of aragonite, another crystalline form of calcium carbonate. The formation of each of the two crystal types is accompanied by the synthesis of specific polyanionic proteins1–3, suggesting that cooperative interactions between these proteins and the… 
Structural changes in a protein fragment from abalone shell during the precipitation of calcium carbonate.
TLDR
This report represents one of the first studies on the conformational changes of a protein fragment that is involved in biomineralization processes on moving from the solution phase into the mineral phase and indicates that GP controls the precipitation kinetics and morphology of calcium carbonate crystals.
Characterization of two molluscan crystal‐modulating biomineralization proteins and identification of putative mineral binding domains
TLDR
Two proteins isolated from the aragonitic component of nacre of the red abalone, Haliotis rufescens, are characterized, demonstrating that protein fractions enriched in AP7 and AP24 produced CaCO3 crystals with morphology distinct from crystals grown in the presence of the total mixture of soluble aragonite‐specific proteins.
Sequential switch of biomineral crystal morphology using trivalent ions
TLDR
A new strategy by which sequential addition or depletion of inorganic trivalent ions in a supersaturated solution can be used to switch the surface morphology of calcium oxalate monohydrate (COM) back and forth, resulting in either the growth of flat crystalline sheets or of nanostructures oriented perpendicular to the surface.

TLDR
The study shows that there is a common basis for understanding these mineralization processes which is reflected in the nature of the protein-crystal interactions which occur in each tissue.
