β-Hydroxyaspartic acid in siderophores: biosynthesis and reactivity
A growing number of siderophores are found to contain β-hydroxyaspartic acid (β-OH-Asp) as a functional group for Fe(III) coordination, along with...

Isolation and identification of siderophores produced by cyanobacteria
Cyanobacteria are one of the most successful and oldest forms of life that are present on Earth. They are prokaryotic photoautotrophic microorganisms...
-
Multiple siderophores: bug or feature?
It is common for bacteria to produce chemically diverse sets of small Fe-binding molecules called siderophores. Studies of siderophore bioinorganic...

An overview of siderophores for iron acquisition in microorganisms living in the extreme
Siderophores are iron-chelating molecules produced by microbes when intracellular iron concentrations are low. Low iron triggers a cascade of gene...
