Bacterial Iron Uptake Pathway

The bacterial iron uptake pathway encompasses a set of molecular mechanisms that bacteria use to acquire iron from their environment, which is essential for their growth and pathogenicity. Iron is often limited in biological systems due to its low solubility and sequestration by host proteins, so bacteria have evolved specialized systems to scavenge, transport, and utilize this critical nutrient. This pathway represents an attractive target for antimicrobial development because blocking it can starve pathogens of an essential nutrient without affecting human cells directly. Components include siderophores, outer membrane receptors, periplasmic binding proteins, and ABC transporters.
