Statistical analysis of multiple amino acid sequence comparisons places the H+/sugar–symporter–uniporter family in the uniporter–symporter–antiporter (USA) superfamily, also known as the major facilitator superfamily (MFS).doi:10.1016/B978-012303965-1/50025-1Jeffrey Griffith...
When antiporters become symporters orvice versa A well-coupled antiporter should be immobile in its conformational transitions except in the presence of one of the two substrates. Just like forsymporters, the canonical is not always the reality, and loose coupling may give rise to promiscuous funct...
C. antiporter Membrane Transport Proteins: Membrane transport proteins are either attached peripherally to the plasma membrane or present deeply embedded into the plasma membrane. These proteins transport molecules or ions that cannot cross the plasma membrane al...
