Abstract excerpt
The regulatory mechanisms of riboflavin biosynthesis in the resting cells of a riboflavin-adenine-deficient mutant of Bacillus subtilis were examined. The growth and pH of the medium remained unchanged in spite of the administration of 0-200 microg/mL riboflavin to the medium during incubation of the resting cells for 17 h. However, the formation of 6,7-dimethyl-8-ribityllumazine (DMRL) and flavin adenine...
