Structural and Stereochemical Elucidation of Cyanochelin C, a Siderophore Associated with Novel Class of Cyanobacterial Acyl Hydrolases

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.

Utilization of cyanobacterial siderophore cyanochelin B by phylogenetically distant heterotrophs suggest its role in mediating microbial interactions

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

Metabolic cost as a determinant of light quality acclimation: a full-PAR characterization of the CA3 cyanobacterium Nostoc sp. CCAP 1453/38

This study characterizes the spectral acclimation strategies of a CA3 cyanobacterium across the full PAR range, showing that metabolic cost influences the type of light quality response.

Cyanochelin B: A siderophore produced by cyanobacterium Leptolyngbya sp. NIES-3755 with photolytic properties that negate iron monopolization in the UV-light

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.
