From: Reprogramming Escherichia coli for the production of prenylated indole diketopiperazine alkaloids
Diversity of indole DKP alkaloid prenylation. (a) The chemical structures of diverse prenylated indole DKP alkaloids are shown. The DKP ring is coloured in pink and bonds involving atoms of the prenyl subunits are colored in blue. (b) Numbering of the indole ring (N1 to C7) and DMAPP (C1’ to C5’) is indicated. The chemical structures of the allylic moiety resulting from regular prenylation and reverse prenylation are shown. Dashed lines indicate the site of attachment to the indole ring.
