Structural basis for substrate binding and specificity of a sodium-alanine symporter AgcS [Biophysics and Computational Biology]

The amino acid, polyamine, and organocation (APC) superfamily is the second largest superfamily of membrane proteins forming secondary transporters that move a range of organic molecules across the cell membrane. Each transporter in the APC superfamily is specific for a unique subset of substrates, even if they possess a similar...
