WebbSiderophores are compounds produced by bacteria, fungi and graminaceous plants for scavenging iron from the environment. They are low-molecular-weight compounds (500–1500 daltons) possessing a high affinity for iron ( III) ( Kf > 10 30 ), the biosynthesis of which is regulated by iron levels and the function of which is to supply iron to the cell.
