Insights into the pH-dependent reactivity and substrate induced active-site reorganization of the non- heme iron enzyme CthEgtB
{{output}}
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 circular dichroism (CD), d... ...
