CC -!- FUNCTION: Catalyzes the dismutation of two molecules of 6,7-dimethyl-8-
CC ribityllumazine, resulting in the formation of riboflavin and 5-amino-
CC 6-(D-ribitylamino)uracil. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 6,7-dimethyl-8-(1-D-ribityl)lumazine + H(+) = 5-amino-6-(D-
CC ribitylamino)uracil + riboflavin; Xref=Rhea:RHEA:20772,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:15934, ChEBI:CHEBI:57986,
CC ChEBI:CHEBI:58201; EC=2.5.1.9;
CC -!- PATHWAY: Cofactor biosynthesis; riboflavin biosynthesis; riboflavin
CC from 2-hydroxy-3-oxobutyl phosphate and 5-amino-6-(D-
CC ribitylamino)uracil: step 2/2.
CC -!- SUBUNIT: Homotrimer. {ECO:0000250}.
