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}.
CC -!- SIMILARITY: Belongs to the uroporphyrinogen-III synthase family.
CC {ECO:0000256|ARBA:ARBA00008133, ECO:0000256|RuleBase:RU366031}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
