2.5.1.106 tryprostatin B synthaseIUBMB Comments
The enzyme from the fungus Aspergillus fumigatus can also prenylate other tryptophan-containing cyclic dipeptides. Prenylation occurs mainly at C-2 , but also at C-3 . Involved in the biosynthetic pathways of several indole alkaloids such as tryprostatins, cyclotryprostatins, spirotryprostatins, fumitremorgins and verruculogen.

enzyme catalyzes also regular C3-prenylation as side reaction. Prenylation products at C2 and C3 are independently formed during the enzyme reaction. Both C2- and C3-prenylations may begin simultaneously with the attack of the electron-rich indole ring at C2 and C33 to C1' of the dimethylallyl cation. Their ratio would be dependent on the position of a given aromatic substrate and accordingly the distance of C2 to C1' as well as C3 to C1'

the reaction is most likely initiated by hydrolysis of the phosphoric acid ester bond to form the dimethylallylic cation and a diphosphate group. The resulting carbocation would be stabilized from two sides by cation-pi interactions with aromatic ring systems, one from the substrate brevianamide F and one from the side chain of Y382. The stabilized cation can then undergo a nucleophilic attack from an aromatic nucleus such as that of the indole. The reactivity of the indole is likely enhanced by a hydrogen bond from its N-1 nitrogen to the side chain carboxylate of E102

a mechanism involving a C-3 normal prenylation as the first step of the catalysis. The barrier to the Cope rearrangement can be quite low, and it can readily proceed at room temperature in these biologically relevant systems. The slowest step in this nonenzymatic reaction might be ring opening of the hexahydropyrroloindole aminal

comparison of mechanisms of the indole alkaloid prenyltransferases. Tryprostatin B synthase catalyzes the normal C-2 prenylation of the indole ring in brevianamide F (cyclo-L-Trp-L-Pro). Mechanism includes an initial C-3 prenylation (either normal or reverse) followed by carbo cation rearrangements to give product

the C5-C8 and C2-C9 reaction channels have very similar activation parameters for the prenylation step. Hence, the final proton ransfer/cyclization step is the product-determining step, with the deprotonation of the C5-C8 intermediate being nearly without activation (0.5 kcal/mol), while the deprotonation process for the C2-C9 pathway has a substantial barrier (higher than the C5-C8 and C2-C9 intermediate states) of 16.8 kcal/mol, resulting in the exclusive formation of the wild-type product tryprostatin B. The diphosphate anion leaving group is stabilized throughout by Arg113, Lys201, Tyr205, Gln380, Lys294, Tyr450, and nine crystal water molecules in the active site

enzyme catalyzes also regular C3-prenylation as side reaction. Prenylation products at C2 and C3 are independently formed during the enzyme reaction. Both C2- and C3-prenylations may begin simultaneously with the attack of the electron-rich indole ring at C2 and C33 to C1' of the dimethylallyl cation. Their ratio would be dependent on the position of a given aromatic substrate and accordingly the distance of C2 to C1' as well as C3 to C1'
