dinG | LexA regulated (SOS) repair enzyme; DNA-dependent ATPase and 5'-3' DNA helicase. (714 aa) | ||||
lexA | SOS response regulator; Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. Binds to the 16 bp palindromic sequence 5'-CTGTATATATATACAG-3'. In the presence of single- stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair. (202 aa) | ||||
dinI | DNA damage-inducible protein I; Inhibits UmuD processing; similar to E. coli damage-inducible protein I (AAC74145.1); Blastp hit to AAC74145.1 (81 aa), 85% identity in aa 1 - 81. (81 aa) |
