All the structural genes of riboflavin biosynthesis are shown to be located on the 2.8 MD DNA fragment, using the collection of plasmids, carrying the Bacillus subtilis riboflavin operon fragments and Bacillus subtilis strains, containing various deletions of rib-operon for analysis. The proximal Bgl II site is shown to be located between promoter P1 and the first structural gene ribG. The distal Hind III site of fragment C is the left bound of the rib-operon.
