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.
