Metal Transporters and Metal Sensors: How Coordination Chemistry Controls Bacterial metall Homeostasis
1. Introduction
The transition or d-block metal ions manganese, iron, cobalt, nickel, copper, zinc, and to a more specialized degree, molybdenum, tungsten and vanadium, have been shown to be important for biological systems. These metal ions are ubiquitously found in natur, nearly exclusively as constituents of proteins.1 The unique properties of metal ions have been exploited by nature to perform a wide range of tasks. These include roles as structural components of biomolecules, as signaling molecules, as catalytic cofactors in reversible oxidation-reduction and hydrolytic reactions, and in structural rearrangements of organic molecules and electron transfer chemistry.1 Indeed, metal ions play critical roles in the cell that cannot be performed by any other entity, and are therefore essential for all of life. However, an individual metal ion is capable of performing only

America First Does Not Mean Europe Alone
There is a widespread view in Europe and beyond that the United States, led by a new Trump administration, will work against the rest of the world—and Europe in particular. (Indeed, when Internationale Politik Quarterly first approached me to write the scene setter for this issue, the initial placeholder title for this article was “The United States vs. the World: The Second Trump Administration and the Future of Transatlantic Relations.”)
Many American progressives, some European leaders, and a range of international observers appear to hold this view, believing that President Donald Trump is inherently hostile to Europe as a result of his “America First” focus. Such beliefs manifested in the many pre-election conversations about the need to “Trump-proof” transatlantic institutions, especially NATO.
Indeed, Trump does not see the United States as the world’s “indispensable defender” (as The Economistput it in January), and he i
