Chain A,B (CAH2_BOVIN | P00921)

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:0038166	angiotensin-activated signaling pathway	The series of molecular signals generated as a consequence of angiotensin II binding to an angiotensin receptor on the surface of the cell, and proceeding with the activated receptor transmitting the signal to a heterotrimeric G-protein complex to initiate a change in cell activity. Ends with regulation of a downstream cellular process, e.g. transcription.
	GO:0006730	one-carbon metabolic process	The chemical reactions and pathways involving the transfer of one-carbon units in various oxidation states.
	GO:2001150	positive regulation of dipeptide transmembrane transport	Any process that activates or increases the frequency, rate or extent of dipeptide transmembrane transport.
	GO:0044070	regulation of anion transport	Any process that modulates the frequency, rate or extent of the directed movement of anions, atoms or small molecules with a net negative charge into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
	GO:0051453	regulation of intracellular pH	Any process that modulates the internal pH of a cell, measured by the concentration of the hydrogen ion.
cellular component
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
	GO:0005886	plasma membrane	The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
