Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (CAH7_HUMAN | P43166)
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.
biological process
    GO:0015701    bicarbonate transport    The directed movement of bicarbonate into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0006730    one-carbon metabolic process    The chemical reactions and pathways involving the transfer of one-carbon units in various oxidation states.
    GO:0032849    positive regulation of cellular pH reduction    Any process that activates or increases the frequency, rate, or extent of a process that reduces the internal pH of a cell.
    GO:0002230    positive regulation of defense response to virus by host    Any host process that results in the promotion of antiviral immune response mechanisms, thereby limiting viral replication.
    GO:0098779    positive regulation of macromitophagy in response to mitochondrial depolarization    The macromitophagy process that is triggered by a detection of the loss of mitochondrial membrane potential.
    GO:0032230    positive regulation of synaptic transmission, GABAergic    Any process that activates, maintains or increases the frequency, rate or extent of GABAergic synaptic transmission, the process of communication from a neuron to another neuron across a synapse using the neurotransmitter gamma-aminobutyric acid (GABA).
    GO:2001225    regulation of chloride transport    Any process that modulates the frequency, rate or extent of chloride transport.
    GO:0098792    xenophagy    The macroautophagy process in which a region of cytoplasm containing an intracellular pathogen or some part of an intracellular pathogen (e.g. viral capsid) is enclosed in a double membrane bound autophagosome, which then fuses with the lysosome leading to degradation of the contents.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
