Enzyme X is a highly pigmented protein that imparts the characteristic color to certain blue-green algae. It also facilitates a reaction necessary to the survival of this species; we can follow the kinetics of this reaction by measuring the conversion of Substance X to Substance Y at various times during purification.
1. Given a pure preparation of these algae, and the required supplies and equipment, devise and outline an empirical procedure for purifying Enzyme X.
2. What is a good indication of purity in your preparation?
