An allosteric enzyme that follows the concerted model has an allosteric coefficient (T/R) of 300 in the absence of substrate.
Suppose that a mutation reversed the ratio.
Select the effects this mutation will have on the relationship between the rate of the reaction (V) and substrate
concentration, [S].
ㅁㅁㅁ
The enzyme would likely follow Michaelis-Menten kinetics.
The plot of V versus [S] would be sigmoidal.
The enzyme would mostly be in the T form.
The plot of V versus [S] would be hyperbolic.
The enzyme would be more active.
Penicillin is hydrolyzed and thereby rendered inactive by penicillinase (also
known as ẞ-lactamase), an enzyme present in some penicillin-resistant
bacteria. The mass of this enzyme in Staphylococcus aureus is 29.6 kDa.
The amount of penicillin hydrolyzed in 1 minute in a 10.0 mL. solution
containing 1.00 x 10 g of purified penicillinase was measured as a
function of the concentration of penicillin. Assume that the concentration of
penicillin does not change appreciably during the assay.
Plots of V versus [S] and 1/V versus 1/[S] for these data are shown.

- 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.

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.
