CC   -!- FUNCTION: Catalyzes the synthesis of the hydroxymethylpyrimidine
CC       phosphate (HMP-P) moiety of thiamine from aminoimidazole ribotide (AIR)
CC       in a radical S-adenosyl-L-methionine (SAM)-dependent reaction.
CC       {ECO:0000255|HAMAP-Rule:MF_00089}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=5-amino-1-(5-phospho-beta-D-ribosyl)imidazole + S-adenosyl-L-
CC         methionine = 4-amino-2-methyl-5-(phosphooxymethyl)pyrimidine + 5'-
CC         deoxyadenosine + CO + formate + 3 H(+) + L-methionine;
CC         Xref=Rhea:RHEA:24840, ChEBI:CHEBI:15378, ChEBI:CHEBI:15740,
CC         ChEBI:CHEBI:17245, ChEBI:CHEBI:17319, ChEBI:CHEBI:57844,
CC         ChEBI:CHEBI:58354, ChEBI:CHEBI:59789, ChEBI:CHEBI:137981;
CC         EC=4.1.99.17; Evidence={ECO:0000255|HAMAP-Rule:MF_00089};
CC   -!- COFACTOR:
CC       Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00089};
CC       Note=Binds 1 [4Fe-4S] cluster per subunit. The cluster is coordinated
CC       with 3 cysteines and an exchangeable S-adenosyl-L-methionine.
CC       {ECO:0000255|HAMAP-Rule:MF_00089};
CC   -!- PATHWAY: Cofactor biosynthesis; thiamine diphosphate biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00089}.
CC   -!- SIMILARITY: Belongs to the ThiC family. {ECO:0000255|HAMAP-
CC       Rule:MF_00089}.
