Context-Dependent Chemoselectivity of Aromatic C-Methyltransferases. [PDF]

Chembiochem
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 ...
