Acetone precipitation is usually the first purification step with a
crude cell lysate. If it works, fine. If not, you use something else.
But you can use acetone powders to reconstitute glycolysis, so the
number of enzymes surviving it can not be that small. The trick is to
add very cold acetone (-20 degrees) very slowly to the well stirred
lysate, and do all centrifugation and preparation steps at -5 degrees.
