Ergothioneine biosynthesis relies on the non-heme Fe(II) sulfoxide synthase EgtB, which couples O₂ activation to stereoselective C-S bond formation between trimethylhistidine (TMH; hercynine) and L-cysteine (L-Cys). Here, we utilize circul...
Lysine or histidine? examining the role of the proximal ligand at the active heme center of cytochrome c nitrite reductase [0.03%]
