Figure 6From: The evolution of metazoan α-carbonic anhydrases and their roles in calcium carbonate biomineralizationDetails of 17 LCDs of α-CAs/nacreins from invertebrate species. Three categories sharing likely homology are indicated (black boxes): C-term basic LCDs in the sponge A. willeyana (highlighted in pink), acidic GXN repeated domains in bivalves (highlighted in blue) and acidic LCDs in the two species of gastropods Haliotis (highlighted in green).Back to article page
