CC hydroxymethylbilane, to the macrocyclic uroporphyrinogen III.
CC {ECO:0000256|RuleBase:RU366031}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=hydroxymethylbilane = H2O + uroporphyrinogen III;
CC Xref=Rhea:RHEA:18965, ChEBI:CHEBI:15377, ChEBI:CHEBI:57308,
CC ChEBI:CHEBI:57845; EC=4.2.1.75;
CC Evidence={ECO:0000256|ARBA:ARBA00000783,
CC ECO:0000256|RuleBase:RU366031};
CC -!- PATHWAY: Porphyrin-containing compound metabolism; protoporphyrin-IX
CC biosynthesis; coproporphyrinogen-III from 5-aminolevulinate: step 3/4.
CC {ECO:0000256|ARBA:ARBA00004772, ECO:0000256|RuleBase:RU366031}.
