CC Name=dipyrromethane; Xref=ChEBI:CHEBI:60342;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00260};
CC Note=Binds 1 dipyrromethane group covalently. {ECO:0000255|HAMAP-
CC Rule:MF_00260};
CC -!- PATHWAY: Porphyrin-containing compound metabolism; protoporphyrin-IX
CC biosynthesis; coproporphyrinogen-III from 5-aminolevulinate: step 2/4.
CC {ECO:0000255|HAMAP-Rule:MF_00260}.
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00260}.
