Chapter 9, Problem 5P
Interpretation Introduction
Interpretation:
An explanation corresponding to the fact that the mutation of the proton-shuttle residue His
Concept introduction:
Mutation is defined as the change in the sequence/order of DNA bases. It occurs due to the introduction of radiation, chemicals, or an internal disorder. Mutation may be caused by a single change in base sequence.

Instructions.
Given each set of information which may include common name(s) and the reaction catalyzed, you are required to identify the main class of the specific enzyme described.
Name: citryl-CoA synthetase
Reaction: ATP + citrate + CoA = ADP + phosphate + (3S)-citryl-CoA
Name: D-xylulose reductase
Reaction: xylitol + NAD+ = D-xylulose + NADH + H+
Name: cellobiose phosphorylase
Reaction: cellobiose phosphate = α-D-glucose 1-phosphate + D-glucose
Name: carbonic anhydrase
Reaction: H2CO3 = CO2 + H2O
Other info: The enzyme catalyzes the reversible hydration of gaseous CO2 to carbonic acid, which dissociates to give hydrogencarbonate above neutral pH.
Name: pantoate activating enzyme
Reaction: ATP + (R)-pantoate = AMP + diphosphate + (R)-pantothenate.

- not true about the Michaelis-Menten equation?

Which of the following is a) for [S] << Km, V = Vmax applies to most enzymes, but allosteric enzymes have different kinetics when [S] = Km, then v = Vmax/2 gives the rate when the enzyme concentration, temperature, pH, and ionic strength are constant for very high values of [S], v approaches Vmax e) Which is correct about the constant Km in the Michaelis-Menten equation? also called the catalytic constant or turnover number equal to the number of product molecules produced per unit time when the enzyme is saturated with substrate it is the constant in the first order rate equation v = k[A] it is the constant in the second order rate equation v = equal to the substrate concentration at which the velocity or rate of a reaction is ½ the…arrow_forwardENZYME KINETICS ANALYSIS of 6 Xanthine oxidase (XO) is the enzyme that catalyzes the synthesis of uric acid, which in excess causes gouty arthritis.

What constitutes the active site of an enzyme? What are the turnover number (kcat), the Michaelis constant (Km), and the maximal velocity (Vmax) of an enzyme? The kcat (catalytic rate constant) for carbonic anhydrase is 5 × 105 molecules per second. This is a “rate constant,” but not a “rate.” What is the difference? By what oncentration would you multiply this rate constant in order to determine an actual rate of prod- uct formation (V)? Under what circumstances would this rate become equal to the maximal velocity (Vmax) of the enzyme?arrow_forward
- 1. pH Effects a. In the enzyme mechanism of lysozyme, two acidic amino acid residues, Asp52 and Glu35, are critical for catalytic activity. If we assume normal side chain pKa values for Asp (pKar = 3.90) and for Glu (pKar = 4.07), what proportion of enzyme molecules will have both Asp52 and Glu35 in the correct ionization state at pH 5.0 (the pH optimum for lysozyme)? b.

O The proton gradient is involved in the release of bound ATP from the synthase as a result of conformational change. O The conformational states interconvert as a result of proton flux through the synthase. There are two sites for substrate on the synthase and two possible conformational states: open (0) and tight-binding (T). Dinitrophenol binds to and inhibits ATP synthase conformational changes, thus inhibiting ATP synthesis. The Fo portion of ATP synthase acts as a rotary motor.arrow_forward
