title: Mg2+ channel selectivity probed by EPR.
abstract: The functionally important extracellular loop is not resolved in the crystal structures of a putative bacterial Mg(2+) channel CorA. In this issue, Dalmas et al. use EPR to determine a structural model for this conserved loop, providing new insight into the ion selectivity.
