Ra. Kreneva et al., Analysis of the operator-like structure that regulates the Bacillus subtilis ribC gene activity, RUSS J GEN, 35(3), 1999, pp. 335-337
A point mutation ( C --> A substitution) in the -35 region of a putative pr
omoter-operator site TTGCCG-17n-TACATT results in a more than 25-fold incre
ase in the activity of ribC gene encoding the bifunctional enzyme-flavokina
se/FAD-synthase-in Bacillus subtilis.
