CC   -!- FUNCTION: Catalyzes the transfer of the AMP portion of ATP to flavin
CC       mononucleotide (FMN) to produce flavin adenine dinucleotide (FAD)
CC       coenzyme. {ECO:0000255|HAMAP-Rule:MF_02115}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + FMN + H(+) = diphosphate + FAD; Xref=Rhea:RHEA:17237,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019,
CC         ChEBI:CHEBI:57692, ChEBI:CHEBI:58210; EC=2.7.7.2;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_02115};
CC   -!- COFACTOR:
CC       Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_02115};
CC   -!- PATHWAY: Cofactor biosynthesis; FAD biosynthesis; FAD from FMN: step
CC       1/1. {ECO:0000255|HAMAP-Rule:MF_02115}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_02115}.
CC   -!- SIMILARITY: Belongs to the archaeal FAD synthase family.
CC       {ECO:0000255|HAMAP-Rule:MF_02115}.
