To elucidate the fundamental structural and chemical principles underlying highly selective ion transport through cellular and organellar membranes.
Examined atomic-resolution structures of biological ion channels and active transport pumps selective for sodium, potassium, calcium, and chloride.
Analyzed the structural architecture and chemical coordination environments lining the ion conduction pathways.
Atomic structures demonstrate that transport selectivity is governed by the specific spatial geometry and chemical composition of the conduction pore.
Identified distinct structural motifs that coordinate and discriminate between biologically prevalent monovalent cations, divalent cations, and anions.
