One more piece towards the microbial "IronNet": In G+ bacteria, the PBP2 receptor is the siderophore-specificity determinant. But, it can be located half a genome away from the synthetase. The solution? Transcriptional co-regulation:

Systematic characterization of PBP2 as the primary siderophore recognizer in Actinomycetes and other Gram-positive bacteria
Iron is a scarce yet essential nutrient for bacteria. Microbes often acquire iron by secreting siderophores, a diverse group of small molecules that form high-affinity complexes with iron for microbia...
