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.
