== Function ==
[https://www.uniprot.org/uniprot/RISB_AQUAE RISB_AQUAE] Catalyzes the formation of 6,7-dimethyl-8-ribityllumazine by condensation of 5-amino-6-(D-ribitylamino)uracil with 3,4-dihydroxy-2-butanone 4-phosphate. This is the penultimate step in the biosynthesis of riboflavin.<ref>PMID:12603336</ref> <ref>PMID:11237620</ref>
