CC -!- FUNCTION: Tetrapolymerization of the monopyrrole PBG into the
CC hydroxymethylbilane pre-uroporphyrinogen in several discrete steps.
CC {ECO:0000256|HAMAP-Rule:MF_00260}.
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 Evidence={ECO:0000256|HAMAP-Rule:MF_00260};
CC -!- COFACTOR:
CC Name=dipyrromethane; Xref=ChEBI:CHEBI:60342;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00260};
CC Note=Binds 1 dipyrromethane group covalently. {ECO:0000256|HAMAP-
CC Rule:MF_00260};
CC -!- MISCELLANEOUS: The porphobilinogen subunits are added to the
CC dipyrromethane group. {ECO:0000256|HAMAP-Rule:MF_00260}.
CC -!- SIMILARITY: Belongs to the HMBS family. {ECO:0000256|ARBA:ARBA00005638,
CC ECO:0000256|HAMAP-Rule:MF_00260}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:KUO86927.1}.
