The iron-thiol-oxygen nexus for iron flux from bare and ferritin-caged minerals and safeguarding DNA: the impact of the thiol structure and protein coat.

The interplay between iron, sulfur, and oxygen underpins the redox regulation of iron across biological and geochemical systems. Prior to the great oxygenation event (GOE), sulfur fostered a reducing environment essential for Fe2+ bioavailability. Po…
