Chain A,B (HEM2_HUMAN | P13716)

molecular function
	GO:0003824	catalytic activity	Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
	GO:0042802	identical protein binding	Interacting selectively and non-covalently with an identical protein or proteins.
	GO:0032791	lead ion binding	Interacting selectively and non-covalently with lead (Pb) ions.
	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:0004655	porphobilinogen synthase activity	Catalysis of the reaction: 2 5-aminolevulinate = 2 H(2)O + H(+) + porphobilinogen.
	GO:0008270	zinc ion binding	Interacting selectively and non-covalently with zinc (Zn) ions.

	GO:0006779	porphyrin-containing compound biosynthetic process	The chemical reactions and pathways resulting in the formation of any member of a large group of derivatives or analogs of porphyrin.

	GO:0051260	protein homooligomerization	The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of identical component monomers. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer.
