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.

The paper identifies V-ATPase inhibition as a trigger for apoptosis via GCN1/GCN2 kinase signaling and MCL-1 depletion, revealing a therapeutic target in certain cancers.

This paper uses random UV mutagenesis to create Chlorella vulgaris mutants with reduced chlorophyll and increased lutein, suitable for food industry applications.

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.
