Insulysin (EC (Also called insulinase, insulin-degrading enzyme, insulin protease, insulin proteinase, insulin-degrading neutral proteinase, insulin-specific protease, insulin-glucagon protease, metalloinsulinase, IDE) is an enzyme.[1][2][3][4][5] This enzyme catalyses the degradation reaction of insulin, glucagon and other polypeptides.

This cytosolic enzyme is present in mammals and in many arthropods such as the fly Drosophila melanogaster.
