Question
Chapter 26, Problem 18P
Interpretation Introduction
Interpretation:
The structure corresponding to the MWC R-state and T-state needs to be determined.
Concept introduction:
Beta sheet structure or five −sheet strand is comprises of two parallel strand and one anti-parallel strand and these two strands are joined by the other two parallel strands and this sheet structure is used as the CTP binding site. A sheet can also be represent in the other form which consists of four stranded sheet and two − alpha helices. Therefore, structure consists three layers which are sheet, helix and sheet.

Consider the role of Histidine in the Serine protease mechanism and sketch a plot showing
the predicted pH profile of chymotrypsin which has a pH optimum of approximately ~8. The pk,
for the His in the catalytic triad is 7.3 in free chymotrypsin which increases to greater than 8 with
a bound peptide. Be sure to label the plot axes and indicate the pka of His on the plot,

Assume the enzyme concentration is equal across all samples (and is equal to 1).
(Answer a and b only)a. Which enzyme will have the highest V0 at very high substrate concentrations? (1 M). Why?
b. Which will have the highest V0 at very low substrate concentrations (5.0 × 10^−12). Why?
. The optimal conditions for salivary lysozyme (hydrolyzing glycoproteins of bacterial
wall) are 37 C - temperature and pH is 5.2. Explain the decrease in this enzyme
activity if the temperature will rise up to 60 °C and pH will be changed to 8.0. To
answer the question:
a) draw the graph of the velocity dependency on temperature and pH;
b) calculate the relative enzyme activity if 10 mg of lysozyme catalyzes the
formation of 5 uM of the product per 2 minutes.
