Cyanochelin C, a non-acylated peptide siderophore from Atacama Desert Myxacorys chilensis, was fully stereochemically resolved; its gene cluster carries CcsQ, a putative deacylase from a cyanobacteria-specific, siderophore-linked acylase lineage.

This paper characterizes cyanochelin B, a photolytic siderophore from cyanobacteria, showing it can both monopolize iron and release it under UV light, depending on environmental conditions.
