Question: In E. coli, eight enzymatic steps are involved in the biosynthesis of

arginine from glutamate. The synthesis of the required enzymes is subject to

control by the ArgD protein, which, on its own, binds weakly to a regulatory

sequence just downstream of the promoter regions for these genes. Upon the

addition of excess arginine to the growth medium, the respective mRNA

molecules are no longer produced. What is the likely role of arginine in the

control of these genes?
