6‐DMATSSa and 6‐DMATSSv from Streptomyces strains, in the presence of DMAPP and GPP. C6‐prenylated indole derivatives and dihydroxynaphthalenes with prenylation at the unsubstituted ring were identified as enzyme products of 6‐DMATSSa.

study highlights the biochemical and structural characterization of the L-tryptophan C6 C-prenyltransferase (C-PT) PriB fromStreptomyces sp. RM-5-8. PriB was found to be uniquely permissive to a diverse array of prenyl donors and acceptors including daptomycin. Two additional PTs also produced novel prenylated daptomycins with improved antibacterial activities over the parent drug.
