Definition of the noun Permease
What does Permease mean as a name of something?
noun - plural: permeases
- [enzyme] Any of several enzymes that transport membrane proteins.
Permease: The permeases are membrane transport proteins, a class of multipass transmembrane proteins that facilitate the diffusion of a specific molecule in or out of the cell by passive transport. In contrast, active transporters couple molecule transmembrane transport with an energy source such as ATP or a favorable ion gradient.

The lactose permease is an active transport system, and the energy is provided in the form of a proton motive force developed by the expulsion of protons. The excreted amount of galactose is proportional to the amount of lactose taken up.
