Question
Chapter 30, Problem 6P
Interpretation Introduction
Interpretation:
The prediction of a mutation in the absence of other subunits of RNA polymerase that leads to the binding of σ to the -10 regions should be determined.
Concept introduction:
Non-competitive inhibition can be defined as a type of enzyme inhibition. In this inhibition, usually, the inhibitor diminishes the enzyme activity. The inhibitor gets fixed alike the normal substrate does to the enzyme. It occurs even if it has been previously bound or not to the substrate. Unlike competitive inhibition, non-competitive inhibition cannot be overcome with the additional substrate.

- Consider the reaction. kp S P kg What effects are produced by an enzyme on the general reaction? AG for the reaction increases. The rate constant for the reverse reaction (kr) increases. The reaction equilibrium is shifted toward the products. The concentration of the reactants is increased. The activation energy for the reaction is lowered. The formation of the transition state is promoted.arrow_forwardThe graph displays the activities of wild-type and several mutated forms of subtilisin on a logarithmic scale. The mutations are identified as: • The first letter is the one-letter abbreviation for the amino acid being altered. • The number identifies the position of the residue in the primary structure. ⚫ The second letter is the one-letter abbreviation for the amino acid replacing the original one. • Uncat. refers to the estimated rate for the uncatalyzed reaction. Log₁(S-1) Wild type S221A H64A -5 D32A S221A H64A D32A -10 Uncat. How would the activity of a reaction catalyzed by a version of subtilisin with all three residues in the catalytic triad mutated compare to the activity of the uncatalyzed reaction? It would have more activity, because the reaction catalyzed by the triple mutant is approximately three-fold faster than the uncatalyzed reaction. It would have less activity, because the reaction catalyzed by the triple mutant is approximately 1000-fold slower than the…arrow_forwardB Substrate Product AL Product Substrate Reaction progress- Reaction progress- omplete the passage describing the two reactions.
