N-acetylphenylalaninamide 2. (a) is a substrate of a-chymotrypsin. Draw the structural formula of this molecule, indicate which bond is cleaved in the hydrolytic reaction, and explain from its structure why it is a specific substrate of a-chymotrypsin. What influence does the acetyl group have on the reaction? (b) The table on the right lists initial velocity data for hydrolysis of N-acetylphenylalaninamide catal- yzed by a-chymotrypsin. From the data calculate the value of KM by a graphical method using a rectangular hyperbolic function to relate velocity to substrate con- centration and compare the results to the value obtained by a linear least-squares fit of the data in the form of a double-reciprocal plot.

11 X For the hydrolysis of glucose-6-phosphate, glucose-6-P + H₂O = glucose + Pi AG'°= -13.8 kJ/mol and K'eq = 3.81x10-³ at 25°C. Therefore the [glucose-6- phosphate]/[glucose] ratio is about 1/260 at equilibrium. What is the [glucose-6- phosphate]/[glucose] ratio at equilibrium when this reaction is coupled to ATP hydrolysis in the coupled reaction glucose + ATP = glucose-6-phosphate + ADP and [ATP] = ADP]?
