Riboflavin synthase of Escherichia coli is a homotrimer with a molecular mass of 70 kDa. The enzyme catalyzes the dismutation of 6,7-dimethyl-8-(1'-D-ribityl)-lumazine, affording riboflavin and 5-amino-6-ribitylamino-2,4(1H,3H)-pyrimidinedione. The N-terminal segment (residues 1-87) and the C-terminal segment (residues 98-187) form beta-barrels with similar fold and a high degree of sequence similarity ...
