Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (HEM3_ECOLI | P06983)
molecular function
    GO:0004418    hydroxymethylbilane synthase activity    Catalysis of the reaction: H(2)O + 4 porphobilinogen = hydroxymethylbilane + 4 NH(4)(+).
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
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:0018160    peptidyl-pyrromethane cofactor linkage    The covalent binding of a pyrromethane (dipyrrin) cofactor to protein via the sulfur atom of cysteine forming dipyrrolylmethanemethyl-L-cysteine.
    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.
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.
