MeSH definition : Membrane transporters that co-transport two or more dissimilar molecules in the opposite
direction across a membrane. Usually the transport of one ion or molecule is against
its electrochemical gradient and is powered by the movement of another ion or molecule
with its electrochemical gradient.;
