CC   -!- FUNCTION: Involved in heme d1 biosynthesis (PubMed:8982003). Catalyzes
CC       the decarboxylation of siroheme into didecarboxysiroheme (By
CC       similarity). {ECO:0000250|UniProtKB:I6UH61,
CC       ECO:0000269|PubMed:8982003}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 H(+) + siroheme = 12,18-didecarboxysiroheme + 2 CO2;
CC         Xref=Rhea:RHEA:19093, ChEBI:CHEBI:15378, ChEBI:CHEBI:16526,
CC         ChEBI:CHEBI:60052, ChEBI:CHEBI:140497; EC=4.1.1.111;
CC         Evidence={ECO:0000250|UniProtKB:I6UH61};
CC   -!- PATHWAY: Porphyrin-containing compound metabolism.
CC       {ECO:0000305|PubMed:8982003}.
CC   -!- SUBUNIT: Probably forms a complex composed of NirD, NirL, NirG and
CC       NirH. All proteins are required for the total conversion of siroheme to
CC       didecarboxysiroheme. {ECO:0000250|UniProtKB:I6UH61}.
CC   -!- DISRUPTION PHENOTYPE: The nirDLGH mutant lacks dissimilatory nitrite
CC       reductase (NIR) activity. The NIR activity is restored by adding
CC       purified heme d1. {ECO:0000269|PubMed:8982003}.
CC   -!- SIMILARITY: Belongs to the Ahb/Nir family. {ECO:0000305}.
