Context‐Dependent Chemoselectivity of Aromatic C‐Methyltransferases

open access: yesChemBioChem, Volume 27, Issue 8, April 2026.
Chemoselectivity is context‐dependent: The SAM‐dependent C‐MTs SfmM2 and NapB5 from streptomycetes catalyze the C‐ and/or O‐dimethylation of aromatic substrates, including l‐tyrosine and flavonoids. C‐methylation activity requires precise substrate recognition and positioning to ensure proximity between the target carbon nucleophile and the methyl ...
