CC   -!- FUNCTION: Tetrapolymerization of the monopyrrole PBG into the
CC       hydroxymethylbilane pre-uroporphyrinogen in several discrete steps.
CC       {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + 4 porphobilinogen = hydroxymethylbilane + 4 NH4(+);
CC         Xref=Rhea:RHEA:13185, ChEBI:CHEBI:15377, ChEBI:CHEBI:28938,
CC         ChEBI:CHEBI:57845, ChEBI:CHEBI:58126; EC=2.5.1.61;
CC   -!- COFACTOR:
CC       Name=dipyrromethane; Xref=ChEBI:CHEBI:60342; Evidence={ECO:0000250};
CC       Note=Binds 1 dipyrromethane group covalently. {ECO:0000250};
CC   -!- PATHWAY: Porphyrin-containing compound metabolism; protoporphyrin-IX
CC       biosynthesis; coproporphyrinogen-III from 5-aminolevulinate: step 2/4.
CC   -!- MISCELLANEOUS: The porphobilinogen subunits are added to the
CC       dipyrromethane group. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the HMBS family. {ECO:0000305}.
