EcMR (mutant) complex with corepressor SAM and DNA 2eyi
Met repressor (MR) interacts with the DNA operator (Met box) repressing methionine synthesis. The corepressor of MR is S-adenosyl methionine (SAM) which is a product of methionine synthesis. Binding of SAM to MR increases the repressor affinity to the DNA thus halting methionine synthesis. For additional details see
