Definition of the noun Permease

What does Permease mean as a name of something?

noun - plural: permeases

  1. [enzyme] Any of several enzymes that transport membrane proteins.

Explanation

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.
