diphosphate + 5-(2-trans-pentenyl)-L-tryptophan
show the reaction diagram
-
very low activity, the alkylation shifts from C-4 to C-5 for FgaPT2, which can be explained by the longer chain length and thus deeper extension of 2-pentenyl diphosphate into the reaction chamber in comparison to that of dimethylallyl diphosphate, so that C-1' of the alkyl residue is closer to C-5 than C-4 in FgaPT2

x-ray structure of DMATS, determined at a resolution of 1.76 A is reported. A complex of DMATS with its substrate L-tryptophan and with an analogue of its isoprenoid substrate dimethylallyl diphosphate reveals the structural basis of this enzyme-catalyzed Friedel-Crafts reaction, showing strict regiospecificity for position 4 of the indole nucleus of tryptophan as well as unusual independence of the presence of Mg2+ ions. The 3D structure of DMATS belongs to a rare alpha/beta barrel fold, called prenyltransferase barrel, that is present in a small group of bacterial enzymes with no sequence similarity to DMATS

the combination of the two dimethylallyltryptophan synthases FgaPT2 and 7-DMATS (EC 2.5.1.34 and EC 2.5.1.80) can be successfully used for chemoenzymatic synthesis of the diprenylated derivatives. The potential of recombinant enzymes from secondary metabolite biosynthesis as promising tools for the production of designed compounds is demonstrated

-
prenyltransferases of the dimethylallyl-tryptophan synthase superfamily catalyze Friedel-Crafts alkylation with high flexibility for aromatic substrates, but the high specificity for dimethylallyl diphosphate prohibits their application as biocatalysts
