Abstract excerpt

The riboflavin kinase encoding gene ribR is situated within a 12 genes locus ytmI-ytnM of the Bacillus subtilis chromosome. Here we demonstrate that ribR is transcribed as part of a 10 kb ytmI-ytnM operon. The riboflavin overproduction phenotype of B. subtilis ribC mutant strains, which is a result of the strongly reduced flavokinase activity of the riboflavin kinase/FAD synthetase RibC, was suppressed by ribR...
