Lysine-cysteine "Nitrogen-Oxygen-Sulfur" (NOS) bonds (<scene name='88/883792/6zx4_nos/2'>restore initial scene</scene>) were first reported in 2021 in transaldolases<ref name="wensien2021">PMID: 33953398</ref>. The sidechains of a lysine and a cysteine, joined by an NOS bond, make a covalent linkage between polypeptide chains. For comparison, the [[disulfide bond]] is a far more common type of covalent linkage between polypeptide chains, and the [[isopeptide bond]] is another rare type. | Lysine-cysteine "Nitrogen-Oxygen-Sulfur" (NOS) bonds (<scene name='88/883792/6zx4_nos/2'>restore initial scene</scene>) were first reported in 2021 in transaldolases<ref name="wensien2021">PMID: 33953398</ref>.
