Copper-Mediated Antimicrobial Activity : Targeting Cytochrome c Complexes Across Bacterial Species

This study identifies c-type cytochrome biogenesis as a conserved target of copper toxicity in bacteria, showing Cu disrupts assembly of these complexes across diverse species.

MnSOD Diversifies, while FeSOD Dominates Superoxide Defense in Cyanobacteria

The paper investigates the roles of MnSOD and FeSOD in superoxide defense in cyanobacteria, finding that FeSOD provides the major defense while MnSOD contributes modestly.

Targeted genome editing of the non-model cyanobacterium Cyanothece PCC 7425 via CRISPR/Cas12a

This paper establishes CRISPR/Cas12a as a rapid and efficient genome editing tool for the non-model cyanobacterium Cyanothece PCC 7425, enabling targeted gene deletion and mutant characterization.

Acclimation of photosynthesis began with a Cu-binding superoxide detoxifying enzyme

The paper identifies APE1 as a Cu-binding superoxide detoxifying enzyme essential for photosynthetic acclimation to oxygenic environments.
