What occurs as a result of an abundance of tryptophan in e. Coli?

E. coli trp operon genes are inactivated

Explanation:

E. coli is a bacterium that is found in the normal flora of our intestines, like all living things, it requires feeding for it, it uses tryptophan, therefore it synthesizes it through genes called trp operon, when there is an abundant amount of Tryptophan in your environment does not need to be synthesized so you do not need to use them and these are deferred, in the event that there are shortages of tryptophan, the trp operon are activated, responsible for synthesizing and producing it
