Chain A,B   (HEM2_PSEAE | Q59643)
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: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.
biological process
    GO:0006783    heme biosynthetic process    The chemical reactions and pathways resulting in the formation of heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring, from less complex precursors.
    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. Porphyrin consists of a ring of four pyrrole nuclei linked each to the next at their alpha positions through a methine group.
    GO:0006782    protoporphyrinogen IX biosynthetic process    The chemical reactions and pathways resulting in the formation of protoporphyrinogen IX.
    GO:0033014    tetrapyrrole biosynthetic process    The chemical reactions and pathways leading to the formation of tetrapyrroles, natural pigments containing four pyrrole rings joined by one-carbon units linking position 2 of one pyrrole ring to position 5 of the next.
