| + | [https://www.uniprot.org/uniprot/SALL_SALTO SALL_SALTO] Involved in the biosynthesis of the proteosome inhibitor salinosporamide A (SalA). Catalyzes the halogenation of S-adenosyl-L-methionine (SAM) with chloride to generate 5'-chloro-5'-deoxyadenosine (5'-CIDA) and L-methionine. It can also use bromide and iodide, producing halogenated 5'-deoxyadenosine (5'-XDA) and L-methionine, however no halogenase activity is detected in the presence of fluoride.<ref>PMID:18059261</ref> | ||

| + | == Publication Abstract from PubMed == | ||
| + | A tandem enzymatic strategy to enhance the scope of C-alkylation of small molecules via the in situ formation of S-adenosyl methionine (SAM) cofactor analogues is described. A solvent-exposed channel present in the SAM-forming enzyme SalL tolerates 5'-chloro-5'-deoxyadenosine (ClDA) analogues modified at the 2-position of the adenine nucleobase. Coupling SalL-catalyzed cofactor production with C-(m)ethyl transfer to coumarin substrates catalyzed by the methyltransferase (MTase) NovO forms C-(m)ethylated coumarins in superior yield and greater substrate scope relative to that obtained using cofactors lacking nucleobase modifications. Establishing the molecular determinants that influence C-alkylation provides the basis to develop a late-stage enzymatic platform for the preparation of high value small molecules. | ||
