Final answer:
Isomerases are the class of enzymes that can convert a substrate to its mirror image.
Step-by-step explanation:
The class of enzymes that is able to convert a substrate to its mirror image is called isomerases.
Isomerases are a type of enzyme that catalyze the interconversion of optical and geometric isomers. Isomers are molecules whose structures are nonsuperimposable mirror images. They have the same chemical formula but differ in their arrangement in space.
For example, glyceraldehyde-3-phosphate isomerase catalyzes the interconversion of glyceraldehyde-3-phosphate and dihydroxyacetone phosphate, which are structural isomers of each other.
