Dr Sophie Berland - Probing the mechanical properties and biochemical defence offered by shell matrix proteins in bivalves

Calcium carbonate is paired up with shell matrix proteins in the suited organo-mineral outer shell in molluscs. Advanced knowledge in the shell proteome is achieved with the development of proteomics providing insights in the biological control of biomineralization at the shell side. Four bivalve species of distant kinship were subjected to proteomics for sequence and function pattern analysis of their retrieved shell matrix proteins. Domains ruling for calcification mechanisms, e.g. carbonic anhydrase, chitin binding and tyrosinase remained common in all the species signing sustained calcifying control proteins. Other shell proteins were fitted ...
