The biomineralization of calcium carbonates is a common process in bacteria, however, the underlying molecular mechanisms remain poorly understood. Recently, intracellular biomineralization of amorphous calcium carbonate phases (iACC) has been discovered in environmentally and phylogenetically widespread cyanobacteria. An orphan gene of unknown function, named ccyA and coding for a protein named Calcyanin, has been identified only in these cyanobacteria. My thesis work consisted in developing a genetic approach to analyze the in vivo function of the ccyA gene and determine whether or not the encoded protein is involved in the formation of iACCs. The failure of ccyA deletion attempts in Cyanothece sp. PCC 7425 and Synechococcus sp. PCC 6312...
