You will perform the protocol below for the calf intestinal alkaline phosphatase (CIP) provided. For each reaction, your final enzyme concentration should be 10 nM CIP.
Note: Enzymes purchased are typically labelled with their “units of activity” (U), as this relates to how much enzyme is needed to catalyze a reaction. The 100 nM CIP provided has approximately 3 U/mL and was diluted 1 in 1,000 from a 500 U/mL purchased enzyme.
1) Create a table (similar to the one below) to help you determine and keep track of what to add to each of the cuvettes in which your reactions will be measured. The five different concentrations of PNPP should be: 25, 50, 100, 200, 300 μM. Each reaction will be in a final volume of 1 mL and contain 10 nM alkaline phosphatase.
Concentrations of stock solutions: 1.0 mM PNPP, 100 nM calf intestinal phosphatase

- The rates at various substrate concentrations for an enzyme-catalysed reaction (b) are recorded as follows: 2.5 5.0 10.0 15.0 (S]/10 M 2.2 3.8 5.9 7.1 Vo/ M min Assuming the reaction obeys Michaelis-Menten kinetics, calculate the following values by using Lineweaver-Burk plot () maximum rate, Vmax- (i) Michaelis constant, Km- (ii) turnover number, kz.arrow_forwardFrom a kinetics experiment, Kcat was determined to be 55sec^-1. For the kinetic assay, 0.05mL of a 0.05mg/mL solution of enzyme was used, and the enzyme has a molecular weight of 30,000g/mole. Assume a reaction volume of 3mL. Calculate Vmax (um*min^-1) for the enzyme and catalytic efficiency (in M^-1sec^-1) for the enzyme. The Km for the enzyme was determined to be 8.3*10^-2M.arrow_forwardIdris has successfully extracted enzymatic proteins from the fish viscera (intestines and stomach). After homogenization and centrifugation, he managed to pool the crude enzyme extract. He is characterizing the enzymes. Please help Idris by answering the followingquestions: (a) How do I run the experiment to find the kinetic properties of the enzyme, KMand Vmax? (b) The enzyme decreased in activity in the presence of NaCl. How do I find out if NaCl is a competitive or non-competitive inhibitor? Explain.arrow_forward

Note if you are testing pH, you only need to calculate one enzyme dilution because all other pHs will use the same strategy.arrow_forwardMike has determined that enzyme he is attempting to purify has an isoelectric point of 4.5 (pI = 4.5). He has decided to examine anion exchange chromatography as a potential purification step. He tested out using 2 different buffer and linear NaCl gradient on HPLC (like what you did). His results are shown below. Which buffer should Mike uses for his purification (both buffer has pH higher than enzyme’s pI)? Why?arrow_forward

- An experiment was carried out to measure the reaction rate of hydrolysis of acetylcholme (substrate) with serum enzymes (Eadie, 1949). In the experiment, two experiments were conducted, namely experiment 1 without using a prostigmine inhibitor and experiment 2 using a prostigmine inhibitor at 1.5 x 10^-7 mol/l. the data obtained are: a. Is prostigmine competitive or noncompetitive inhibitor? b. determine the value of km and rmax for the two experiments, comparearrow_forwardDo not give handwriting solution.arrow_forwardA purified protein sample was used in a reaction, resulting in an activity of 696.7 nmol min-1. The reaction volume was 145.0 µL and the final volume before loading the plate was 1,050 µL. The total reaction time was 4.25 min. The amount of protein used in the reaction was 4.270 µg. Calculate the specific activity of the sample (in nmol min-1 µg-1).arrow_forward
