Abstract

A new metal scavenger for bacteria All cells must find a way to acquire trace metals. Bacteria and plants scavenge iron, for instance, by synthesizing and releasing iron-chelating compounds called siderophores. Ghssein et al. describe three enzymes in Staphylococcus aureus that are responsible for the biosynthesis of another type of metallophore (see the Perspective by Nolan). Metabolomics and a range of biochemical assays show that this compound, named staphylopine, is involved in the uptake of a range of metals, depending on the growth environment. The genes required for staphylopine biosynthesis are conserved across a number of pathogenic bacteria and are similar to those for a broad-spectrum metallophore produced by plants.
