La biominéralisation des carbonates de calcium est un processus répandu chez les bactéries. Cependant les mécanismes moléculaires sous-jacents restent mal compris. Récemment, la biominéralisation intracellulaire de phases amorphes de carbonate de calcium (iACC) a été découverte chez des cyanobactéries répandues environnementalement et phylogénétiquement. Un gène orphelin de fonction inconnue, nommé ccyA et codant pour une protéine nommée Calcyanine, a été identifié uniquement chez ces cyanobactéries. Ainsi mon travail de thèse a consisté à développer une approche génétique pour analyser la fonction in vivo du gène ccyA et déterminer si la protéine qu’il code est impliquée ou non dans la formation des iACC. L’échec des tentatives de délétion...
