title: Metal-mediated inhibition is a viable approach for inhibiting cellular methionine aminopeptidase.
abstract: Methionine aminopeptidase (MetAP) plays an essential role for cell survival. Hence, MetAP is a promising target for developing broad spectrum antibacterial agents. MetAP can be activated in vitro by a number of divalent metals, and X-ray structures show that the active site can accommodate two cations. Herein, we demonstrate bacterial growth inhibition by a compound that targets MetAP by recruitment of a third auxiliary metal. Contrary to previous beliefs, this shows that metal-mediated inhibition is a viable approach for discovering MetAP inhibitors that are effective for therapeutic application.
