CC   -!- FUNCTION: Converts heme B (protoheme IX) to heme O by substitution of
CC       the vinyl group on carbon 2 of heme B porphyrin ring with a
CC       hydroxyethyl farnesyl side group. {ECO:0000255|HAMAP-Rule:MF_00154}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2E,6E)-farnesyl diphosphate + H2O + heme b = diphosphate +
CC         Fe(II)-heme o; Xref=Rhea:RHEA:28070, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:33019, ChEBI:CHEBI:60344, ChEBI:CHEBI:60530,
CC         ChEBI:CHEBI:175763; EC=2.5.1.141; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00154};
CC   -!- PATHWAY: Porphyrin-containing compound metabolism; heme O biosynthesis;
CC       heme O from protoheme: step 1/1. {ECO:0000255|HAMAP-Rule:MF_00154}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00154}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00154}.
CC   -!- MISCELLANEOUS: Carbon 2 of the heme B porphyrin ring is defined
CC       according to the Fischer nomenclature. {ECO:0000255|HAMAP-
CC       Rule:MF_00154}.
CC   -!- SIMILARITY: Belongs to the UbiA prenyltransferase family. Protoheme IX
CC       farnesyltransferase subfamily. {ECO:0000255|HAMAP-Rule:MF_00154}.
CC   -!- SEQUENCE CAUTION:
