Some bacteria can excrete a toxin that breaks down sphingomyelin in mammalian erythrocytes, causing those red blood cells to lyse. Examination of the toxin showed it to be an enzyme that could break the phosphoester bond between sphingosine and phosphocholine (ie. the products are ceramide and phosphocholine). The mechanism of the reaction is as follows: The active site of the enzyme contains three critical residues—histidine 296, glutamate 53 and histidine 151. The glu positions a Mg+2 ion near the phosphate....

The enzyme that hydrolyzes acetylcholine to form acetate and choline has a Km = 9 x 10-5 M for the substrate. In an reaction flask with 5 nanomol / mL of the enzyme and 150 µM of acetylcholine, an initial reaction rate of 40 µmol / mLs was observed. a) Calculate vmax for this amount of enzyme. b) Calculate kcat for the enzyme. c) Calculate the catalytic efficiency of the enzyme. d) Does this enzyme approach “catalytic perfection?
