Met repressor
From Proteopedia
Function
Met repressor (MR) interacts with the DNA operator (Met box) repressing methionine synthesis. The coreppressor 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[1]. For additional details see
