Abstract
Fungal aromatic prenyltransferases are a family of biosynthetic enzymes that catalyze the prenylation of a range of aromatic substrates during the biosynthesis of bioactive indole alkaloids, diketopiperazines, and meroterpenoids. Their broad substrate scope and soluble nature make these enzymes particularly adept for applications in biocatalysis; for example, the enzymatic derivatization of aromatic drugs improves their bioactivity. Here, we investigated four putative aromatic prenyltransferases from lichen-forming fungi, an underexplored group of organisms that produce more than 1,000 unique metabolites. We successfully expressed two enzymes, annotated as dimethylallyltryptophan synthases, from two lichen species in the heterologous host A. oryzae. Based on their in vivo activity, we hypothesize that these enzymes are in fact 4-O-dimethylallyl-l-tyrosine synthases. Our extensive bioinformatic analysis further confirmed that these and related lichen aromatic prenyltransferases are likely not active on indoles but rather on aromatic polyketides and phenylpropanoids, major metabolites in lichens. Overall, our work provides new insights into fungal aromatic prenyltransferases at the family level and enables future efforts aimed at identifying new candidates for biocatalytic transformations of aromatic compounds.

Abstract
Prenylation of amino acids is a critical step for synthesizing building blocks of prenylated alkaloid family natural products, where the corresponding prenyltransferase that catalyzes prenylation on free l-histidine (l-His) has not yet been identified. Here, we first discovered and characterized a prenyltransferase FunA from the antifungal agent fungerin pathway that efficiently performs C4-dimethylallylation on l-His. Crystal structure-guided engineering of the prenyl-binding pocket of FunA, a single M181A mutation, successfully converted it into a C4-geranyltransferase. Furthermore, FunA and its variant FunA-M181A show broad substrate promiscuity toward substrates that vary in substituents of the imidazole ring. Our work furthers our knowledge of free amino acid prenyltransferase and expands the arsenal of alkylation biocatalysts for imidazole-containing small molecules.

Abstract
Farnesylated chalcones were favored by researchers due to their different biological activities. However, only five naturally occurring farnesylated chalcones were described in the literature until now. Here, the farnesylation of six chalcones by the Aspergillus terreus aromatic prenyltransferase AtaPT was reported. Fourteen monofarnesylated chalcones (1F1-1F5, 2F1-2F3, 3F1, 3F2, 4F1, 4F2, 5F1, 6F1, and 6F2) and a difarnesylated product (2F3) were obtained, enriching the diversity of natural farnesylated chalcones significantly. Ten of them are C-farnesylated products, which complement O-farnesylated chalcones by chemical synthesis. Fourteen products have not been reported prior to this study. Nine of the produced compounds (1F2-1F5, 2F1-2F3, 5F1, and 6F1) exhibited inhibitory effect on α-glucosidase with IC50 values ranging from 24.08 ± 1.44 to 190.0 ± 0.28 μM. Among them, compounds 2F3 with IC50 value at 24.08 ± 1.44 μM and 1F4 with IC50 value at 30.09 ± 0.59 μM showed about 20 times stronger than the positive control acarbose with an IC50 at 536.87 ± 24.25 μM in α-glucosidase inhibitory assays.

Abstract
UbiA-type prenyltransferases (PTases) are significant enzymes that lead to structurally diverse meroterpenoids. Herein, we report the identification and characterization of an undescribed UbiA-type PTase, FtaB, that is responsible for the farnesylation of indole-containing diketopiperazines (DKPs) through genome mining. Heterologous expression of the fta gene cluster and non-native pathways result in the production of a series of new C2-farnesylated DKPs. This study broadens the reaction scope of UbiA-type PTases and expands the chemical diversity of meroterpenoids.

Abstract
Phloretin is widely found in fruit and shows various biological activities. Here, we demonstrate the dimethylallylation, geranylation, and farnesylation, particularly the first dimethylallylation at the nonaromatic carbon of phloretin (1) by the fungal prenyltransferase AnaPT and its mutants. F265 was identified as a key amino acid residue related to dimethylallylation at the nonaromatic carbon of phloretin. Mutants AnaPT_F265D, AnaPT_F265G, AnaPT_F265P, AnaPT_F265C, and AnaPT_F265Y were discovered to generally increase prenylation activity toward 1. AnaPT_F265G catalyzes the O-geranylation selectively at the C-2' hydroxyl group, which involves an intramolecular hydrogen bond with the carbonyl group of 1. Seven products, 1D5, 1D7-1D9, 1G2, 1G4, and 1F2, have not been reported prior to this study. Twelve compounds, 1D3-1D9, 1G1-1G3, and 1F1-1F2, exhibited potential inhibitory effects on α-glucosidase with IC50 values ranging from 11.45 ± 0.87 to 193.80 ± 6.52 μg/mL. Among them, 1G1 with an IC50 value of 11.45 ± 0.87 μg/mL was the most potential α-glucosidase inhibitor, which is about 30 times stronger than the positive control acarbose with an IC50 value of 346.63 ± 15.65 μg/mL.

Abstract
Prenyltransferases (PTs) are involved in the biosynthesis of a multitude of pharmaceutically and agriculturally important plant, bacterial, and fungal compounds. Although numerous prenylated compounds have been isolated from Basidiomycota (mushroom-forming fungi), knowledge of the PTs catalyzing the transfer reactions in this group of fungi is scarce. Here, we report the biochemical characterization of an O- and C-prenylating dimethylallyltryptophan synthase (DMATS)-like enzyme LpTyrPT from the scurfy deceiver Laccaria proxima. This PT transfers dimethylallyl moieties to l-tyrosine at the para-O position and to l-tryptophan at atom C-7 and represents the first basidiomycete l-tyrosine PT described so far. Phylogenetic analysis of PTs in fungi revealed that basidiomycete l-tyrosine PTs have evolved independently from their ascomycete counterparts and might represent the evolutionary origin of PTs acting on phenolic compounds in secondary metabolism.
