The influence of silicateins on the shape and crystalline habit of silica carbonate biomorphs of alkaline earth metals (Ca, Ba, Sr)

This contribution presents the effect of two ortholog enzymes from marine sponges called silicateins on the formation of silica carbonate biomorphs of alkaline metals (Ca, Ba, Sr). In vivo, these enzymes participate in the polymerization of silica. Silicateins from Tethya aurantia and Suberitis domu...
