This blocking of expression is called repression . Repressor proteins are coded for by regulator gene s. Repressor proteins then attach to a DNA segment known as the operator. By binding to the operator, the repressor protein prevents ... the gene expression, is present, then it can interact with the repressor protein and detach it from ... is a molecule that can bind to repressor and make it bind to the operator tightly, which decreases transcription.

SAM concentration becomes low the repressor dissociates from the operator site allowing more methionine to be produced.

Repressor LexA or LexA is a repressor enzyme EC number 3.4.21.88 that represses SOS response gene s coding for DNA polymerase s required for repairing DNA damage. LexA is intimately linked to RecA in the biochemical cycle of DNA damage and repair. RecA binds to DNA bound LexA causing LexA to cleave itself in a process called proteolysis autoproteolysis . DNA damage can be inflicted by the action of antibiotics. Bacteria require topoisomerase s such as DNA gyrase or topoisomerase IV for DNA replication . Antibiotics such as ciprofloxacin are able to prevent the action of these molecules by attaching themselves to the gyrase DNA complex. This is counteracted by the polymerase repair molecules from the SOS response . Unfortunately the action is partly counterproductive because ciprofloxacin is also involved in the synthetic pathway to RecA type molecules which means that the bacteria responds to an antibiotic by starting to produce more repair proteins. These repair proteins can lead to eventual benevolent mutations which can render the bacteria resistant to ciprofloxacin. Mutations are traditionally thought of as happening as a random process and as a liability to the organism. Many strategies exist in a cell to curb the rate of mutations. Mutations on the other hand can also be part of a survival strategy. For the bacteria under attack from an antibiotic, mutations help to develop the right biochemistry needed for defense. Certain polymerases in the SOS pathway are error prone in their copying of DNA which leads to mutations. While these mutations are often lethal to the cell, they can also lead to mutations which improve the bacteria s survival. In the specific case of topoisomerases, some bacteria have mutated one of their amino acids so that the ciproflaxin can only create a weak bond to the topoisomerase. This is one of the methods that bacteria use to become Antibiotic resistance resistant to antibiotics. Impaired LexA proteolysis has been shown to interfere with ciprofloxacin ... more details
