Uniporters | definition of Uniporters by Medical dictionary
facilitated diffusion (redirected from Uniporters)
the protein-mediated transport of a compound across a biomembrane that is not ion-driven; a saturable transport system.
facilitated diffusion Carrier-mediated transport of a non-charged molecule down its chemical gradient via a specific membrane-integrated protein.
The movement of a substance (such as glucose) through a cell membrane along a concentration gradient with the help of membrane proteins acting as carrier molecules.

Based on transport mode, MFS transporters are divided into three main groups: uniporters
which transport a single substrate; symporters which transport a substrate in association with a coupling ion; and antiporters which transport a substrate and a cosubstrate in opposite directions .
To date, it has been revealed that secondary transporters, including uniporters
, symporters, and antiporters, facilitate tolerance to salt stress through the transportation of a number of ions and secondary metabolic substrates across cytoplasmic or internal membranes in a variety of organisms.
