what determines the substrate specificity of metal ion transporters?
Homework Answers
transporter substrate affinity or specificity is determined by a small number of interactions a given ion can make with the specific binding site of the transporter. Selectivity filters are narrow parts of the pore, the size and charge of which is adapted for a specific ion.
