Neutral sphingomyelinase 2 converts sphingomyelin into ceramide and phosphocholine. Assume its Vmax is 35μMmin−1. When you provide 3×10−5M of sphingomyelin, you observe an initial velocity of 6.0μMmin−1. Calculate the KM for this reaction, rounding to 3 significant figures. Explain the changes in values of Vmax and KM, when 50μM of an uncompetitive inhibitor is added into the reaction mixture.
