WebTwo members of this family are known to catalyse the sequential condensation of isopentenyl pyrophosphate (IPPP) to DMAPP: farnesyl pyrophosphate synthase dimer (FPPS dimer) and geranylgeranyl pyrophosphate synthetase hexamer (GGPPS hexamer) (Kavanaugh et al, 2006). Both enzymes utlise Mg2+ as cofactor (Chang et al. 2024). … WebOct 7, 2009 · Dimethylallyltryptophan synthase is an aromatic prenyltransferase that catalyzes an electrophilic aromatic substitution reaction between dimethylallyl diphosphate (DMAPP) and L-tryptophan. The synthase is found in a variety of fungi, where it catalyzes the first committed step in the biosynthesis of the ergot alkaloids.
