Question

Suppose that the active catalytic site of an enzyme contains amino acid residues at
the following positions:
Residue 124 - Arginine
Residue 318 - Valine
Residue 67 - Glutamate
Residue 251 - Glycine
Which of the following amino acid substitutions would be least likely to affect the
activity of this enzyme?
Lysine at position 124
Aspartate at position 318
Tryptophan at position 251
Asparagine at position 67
A substitution at any of these positions would render the enzyme inactive
88

Expert Solution

Step 1

Introduction :-

Enzymes are biological catalysts that accelerate chemical reactions in cells. They are made up of protein molecules and play a critical role in maintaining the metabolic processes in living organisms. Enzymes work by reducing the activation energy required for a reaction to occur, making it easier for the reaction to take place.
