[UV-induction of the LT-toxin operon depending on genes lexA, recA, and umuD].
UV induction of the elt operon (the LT-toxin operon in Escherichia coli) was demonstrated in experiments using fusion of elt::lac operons with the help of Mud1(Ap lac) phage. UV induction of the elt operon is lexA-dependent; thus, the possibility of SOS regulation of this process may be assumed. However, UV induction of the elt operon turned out to be recA-independent, which makes it impossible to consider this induction as a typical SOS response. UV induction of the elt operon is also observed in Salmonella typhimurium, which differs from E. coli in the product of umuD, which suggests that the UV induction of the elt operon is umuD independent.
