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 -!- SUBUNIT: Monomer. {ECO:0000250}.
CC -!- MISCELLANEOUS: The porphobilinogen subunits are added to the
CC dipyrromethane group. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the HMBS family. {ECO:0000305}.
