Enzyme repressor information

An enzyme repressor is a substance that negatively regulates the amount of an enzyme by decreasing the rate of its biosynthesis. It is the opposite of...

the aconitase is converted to IRPF1, a translation repressor or mRNA stabilizer that represses the formation of iron-binding proteins and favours formation...

present, these tryptophan repressor dimers bind to tryptophan, causing a change in the repressor conformation, allowing the repressor to bind to the operator...
