CC -!- FUNCTION: Catalyzes the formation of 6,7-dimethyl-8-ribityllumazine by
CC condensation of 5-amino-6-(D-ribitylamino)uracil with 3,4-dihydroxy-2-
CC butanone 4-phosphate. This is the penultimate step in the biosynthesis
CC of riboflavin. {ECO:0000256|RuleBase:RU003795}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2S)-2-hydroxy-3-oxobutyl phosphate + 5-amino-6-(D-
CC ribitylamino)uracil = 6,7-dimethyl-8-(1-D-ribityl)lumazine + H(+) + 2
CC H2O + phosphate; Xref=Rhea:RHEA:26152, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:15934, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:58201, ChEBI:CHEBI:58830; EC=2.5.1.78;
CC Evidence={ECO:0000256|ARBA:ARBA00001697,
CC ECO:0000256|RuleBase:RU003795};
CC -!- PATHWAY: Cofactor biosynthesis; riboflavin biosynthesis; riboflavin
CC from 2-hydroxy-3-oxobutyl phosphate and 5-amino-6-(D-
CC ribitylamino)uracil: step 1/2. {ECO:0000256|ARBA:ARBA00004917,
CC ECO:0000256|RuleBase:RU003795}.
CC -!- SIMILARITY: Belongs to the DMRL synthase family.
CC {ECO:0000256|ARBA:ARBA00007424, ECO:0000256|RuleBase:RU003795}.
