General annotation (Comments)

Function

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 By similarity. HAMAP-Rule MF_00178

Catalytic activity

1-deoxy-L-glycero-tetrulose 4-phosphate + 5-amino-6-(D-ribitylamino)uracil = 6,7-dimethyl-8-(D-ribityl)lumazine + 2 H2O + phosphate. HAMAP-Rule MF_00178

Pathway

Cofactor biosynthesis; riboflavin biosynthesis; riboflavin from 2-hydroxy-3-oxobutyl phosphate and 5-amino-6-(D-ribitylamino)uracil: step 1/2. HAMAP-Rule MF_00178

Subunit structure

Forms an icosahedral capsid composed of 60 subunits, arranged as a dodecamer of pentamers By similarity.

Sequence similarities

Belongs to the DMRL synthase family.
