Two thermostable α-carbonic anhydrases (α-CAs) isolated from thermophilic Sulfurihydrogenibium spp., namely SspCA (from S. yellowstonensis) and SazCA (from S. azorense), were shown in a previous work to possess interesting complementary properties. SspCA was shown to have an exceptional thermal stability, whereas SazCA demonstrated to be the most active α-CA known to date for the CO2 hydration reaction. Here we report the crystallographic structure of SazCA and the identification of the structural features responsible for its high catalytic activity, by comparing it with SspCA structure. These data are of relevance for the design of engineered proteins showing higher stability and catalytic activity than other α-CAs known to date.
