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.

The paper functionally characterizes a cyanobacterial TonB-dependent transporter for cyanochelin B uptake and shows its specificity and evolutionary link to other siderophore transport systems.

The paper shows that cyanobacterial siderophore cyanochelin B is used by distant heterotrophs under iron limitation, supporting microbial interactions in soil crust ecosystems.

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.
