  • Title: A Tandem Enzymatic sp2 -C-Methylation Process: Coupling in Situ S-Adenosyl-l-Methionine Formation with Methyl Transfer.
    Author: Sadler JC, Humphreys LD, Snajdrova R, Burley GA.
    Journal: Chembiochem; 2017 Jun 01; 18(11):992-995. PubMed ID: 28371017.
    Abstract:
    A one-pot, two-step biocatalytic platform for the regiospecfic C-methylation and C-ethylation of aromatic substrates is described. The tandem process utilises SalL (Salinospora tropica) for in situ synthesis of S-adenosyl-l-methionine (SAM), followed by alkylation of aromatic substrates by the C-methyltransferase NovO (Streptomyces spheroides). The application of this methodology is demonstrated for the regiospecific labelling of aromatic substrates by the transfer of methyl, ethyl and isotopically labelled 13 CH3,13 CD3 and CD3 groups from their corresponding SAM analogues formed in situ.
