1. an enzyme that facilitates the transport of specific substances across cell membranes
Usage: biochemistry

Examples

• The lactose permease allows bacteria to transport lactose into the cell.
• Researchers studied how the glucose permease functions in yeast cells.
• A defective permease can prevent nutrients from entering the cell.
• The permease undergoes conformational changes during substrate transport.
• Scientists identified a new permease responsible for amino acid uptake.
• The cell membrane contains various permeases for different molecules.
