CC       biosynthesis; coproporphyrinogen-III from 5-aminolevulinate: step 2/4.
CC       {ECO:0000255|HAMAP-Rule:MF_00260}.
CC   -!- MISCELLANEOUS: The porphobilinogen subunits are added to the
CC       dipyrromethane group. {ECO:0000255|HAMAP-Rule:MF_00260}.
CC   -!- SIMILARITY: Belongs to the HMBS family. {ECO:0000255|HAMAP-
CC       Rule:MF_00260}.
