- Considering that genes can code only for RNA orproteins, how can the synthesis of nonprotein substancessuch as carbohydrates or steroids be under geneticcontrol?How do guanine and adenine nucleotides inhibit their own synthesis? How do they promote synthesis of each other?Christian Anfinsen showed that the enzyme Ribonuclease (RNase) is completely inactivated at high concentrations of beta mercaptoethanol (BME). When BME is removed, it restores only approximately 1% of RNase activity. When a very low concentration of BME is added back to RNase, its activity is restored to nearly 100%. Why? a Low concentrations of BME causes disulfide bonds to break, but they randomly reform. b High concentrations of BME disrupt all disulfide bonds, which inactivates the enzyme. At low concentrations all of the disulfide bonds reform and BME acts as a cofactor for the enzyme. c The enzyme is only active when an intermediate number of disulfide bonds exists. which is achieved only at low concentrations of BME. d The low concentration of BME allows the majority of the proteins to adopt their most stable form, which is the active form.
