Asymmetric Unit(hide GO term definitions)
Chain A   (Q3I4V7_CRYNV | Q3I4V7)
molecular function
    GO:0004089    carbonate dehydratase activity    Catalysis of the reaction: H2CO3 = CO2 + H2O.
    GO:0016829    lyase activity    Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
