Chapter 17, Problem 69TQ
Summary Introduction
To review:
The diagram of a phosphodiester linkage in B-DNA, in association with water molecules.
Introduction:
The B-DNA is the physiological form that consists of two polydeoxynucleotide strands thatwind around each other in a right-handed double helix. The DNA have a nitrogenous base (either purine or pyrimidine) attached to the first carbon of deoxyribose sugar. There is a 3’-5’ phosphodiester linkage between two nucleotides in the strand. Each phosphate group can form hydrogen bonds with six water molecules.

- 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. 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.
