One microgram of a pure enzyme (MW = 92,000) catalyzed a reaction at a rate of 0.50 µmoles/min under optimum conditions. Calculate (a) the specific activity of the enzyme in terms of units/mg protein and units/mole, and (b) the turnover number.

Step 1
First, we need to understand what each term means. The specific activity of an enzyme is a measure of the enzyme's ability to convert its substrate into product, expressed as the number of substrate molecules converted per minute per milligram of enzyme. The Show more…

A pure enzyme has a specific activity of 120 units/mg protein. a) Calculate the turnover number if the MW of the enzyme is 360,000. [Units = moles of products/min]. b) Calculate the time required for one catalytic cycle.
Khalida D.
calculate the turnover number of an enzyme, you need to know: Select one: A. the enzyme concentration B. the initial velocity of the catalyzed reaction at [S] >> Km. C. the initial velocity of the catalyzed reaction at low [S]. D. the Km for the substrate. E. both the enzyme concentration and the initial velocity of the catalyzed reaction at [S] >> Km.
