The presence of isolated metal cations, far from any other atom, is not uncommon in protein crystal structures. A systematic survey of the Protein Data Bank showed that nearly 8% of the metal cations are naked, more frequently if they can interact only electrostatically with their neighbors. Surprisingly, this seemed to be only weakly related to the crystallographic resolution.

Abstract
The presence of isolated metal cations, far from any other atom, is not uncommon in protein crystal structures. A systematic survey of the Protein Data Bank showed that nearly 8% of the metal cations are naked, more frequently if they can interact only electrostatically with their neighbors. Surprisingly, this seemed to be only weakly related to the crystallographic resolution.File in questo prodotto:
