The paper identifies 5-thiooxazoles as the cysteine post-translational modifications in bufferins using isotopic labeling and confirms consistency with related MNIO families.

The paper identifies and characterizes the diversity of substrates and partner proteins for multinuclear non-heme iron-dependent oxidative (MNIO) enzymes, revealing new insights into their role in bacterial copper homeostasis and potential broader stress responses.

This paper identifies bufferins, a widespread family of ribosomal peptide metallophores that help bacteria adapt to copper stress by sequestering excess copper ions.
