Four distinct classes of interactions (inter and intramolecular forces) contribute to a protein's tertiary and quaternary structures. Name the interaction then describe the amino acids that can form this type of interaction. Draw and annotate a diagram of the interaction between two amino acids.
Examine the metabolic pathway. The enzymes that catalyze each step are identified as "e" with a numeric subscript.

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.

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_forward
