A mutase is an enzyme of the isomerase class that catalyzes the movement of a functional group from one position to another within the same molecule.{{cite book |last1=Nelson |first1=David |last2=Cox |first2=Michael |title=Lehninger Principles of Biochemistry |date=2008 |publisher=W.H.

Examples of mutases include bisphosphoglycerate mutase, which appears in red blood cells and phosphoglycerate mutase, which is an enzyme integral to glycolysis. In glycolysis, it changes 3-phosphoglycerate to 2-phosphoglycerate by moving a single phosphate group within a single molecule.
