What is the difference between the type of reactions catalyzed by isomerases (narrowly defined) and mutases? Draw a reaction from glycolysis that is an example of each.
Isomerase is a class of enzymes that changes the form of one molecule into other forms by rearrangement of atoms within a molecule. Isomerase could be racemase, epimerase, cis-trans isomerase, etc. While Mutase is a part of isomerase that catalyses those reactions in which there's a change in the position of a group in a molecule which changes it to some other form. Eg: phosphoglycerate mutase which changes 3-phosphoglycerate to 2-phosphoglycerate, by just changing the position of the phosphate group from 3rd carbon to 2nd.
