Premutilin Synthase: Ring Rearrangement by a Class II Diterpene Cyclase.

ABSTRACT: Biosynthesis of the complex diterpenoid antibiotic pleuromutilin relies on a bifunctional (di)terpene synthase, and here site-directed mutagenesis was used to knockout either of the two active sites. This enabled characterization of the novel ring contracted intermediate produced by the initiating class II diterpene cyclase active site. Quantum chemical calculations further indicate the importance of reactant configuration for this intriguing ring rearrangement.

Magnesium-specific ring expansion/contraction catalysed by the class II diterpene cyclase from pleuromutilin biosynthesis.

Project description:The class II diterpene cyclase (DTC) from pleuromutilin biosynthesis uniquely mediates 'A' ring contraction of the initially formed decalin bicycle, yielding mutildienyl diphosphate (MPP). Catalysis requires a divalent metal cation co-factor. Intriguingly, selectively with magnesium, this DTC catalyzes ring expansion/contraction between MPP and halimadienyl diphosphate, providing some catalytic insight.

Higher-order oligomerization of a chimeric αβγ bifunctional diterpene synthase with prenyltransferase and class II cyclase activities is concentration-dependent.

Project description:The unusual diterpene (C20) synthase copalyl diphosphate synthase from Penicillium verruculosum (PvCPS) is the first bifunctional terpene synthase identified with both prenyltransferase and class II cyclase activities in a single polypeptide chain with αβγ domain architecture. The C-terminal prenyltransferase α domain generates geranylgeranyl diphosphate which is then cyclized to form copalyl diphosphate at the N-terminal βγ domain interface. We now demonstrate that PvCPS exists as a hexamer at high concentrations - a unique quaternary structure for known αβγ terpene synthases. Hexamer assembly is corroborated by a 2.41 Å-resolution crystal structure of the α domain prenyltransferase obtained from limited proteolysis of full-length PvCPS, as well as the ab initio model of full-length PvCPS derived from small-angle X-ray scattering data. Hexamerization of the prenyltransferase α domain appears to drive the hexamerization of full-length PvCPS. The PvCPS hexamer dissociates into lower-order species at lower concentrations, as evidenced by size-exclusion chromatography in-line with multiangle light scattering, sedimentation velocity analytical ultracentrifugation, and native polyacrylamide gel electrophoresis experiments, suggesting that oligomerization is concentration dependent. Even so, PvCPS oligomer assembly does not affect prenyltransferase activity in vitro.

Characterization and inhibition of a class II diterpene cyclase from Mycobacterium tuberculosis: implications for tuberculosis.

Project description:Mycobacterium tuberculosis remains a widespread and devastating human pathogen, whose ability to infiltrate macrophage host cells from the human immune system is an active area of investigation. We have recently reported the discovery of a novel diterpene from M. tuberculosis, edaxadiene, whose ability to arrest phagosomal maturation in isolation presumably contributes to this critical process in M. tuberculosis infections. (Mann, F. M., Xu, M., Chen, X., Fulton, D. B., Russell, D. G., and Peters, R. J. (2009) J. Am. Chem. Soc., in press). Here, we present characterization of the class II diterpene cyclase that catalyzes the committed step in edaxadiene biosynthesis, i.e. the previously identified halimadienyl-diphosphate synthase (HPS; EC 5.5.1.16). Intriguingly, our kinetic analysis suggests a potential biochemical regulatory mechanism that triggers edaxadiene production upon phagosomal engulfment. Furthermore, we report characterization of potential HPS inhibitors: specifically, two related transition state analogs (15-aza-14,15-dihydrogeranylgeranyl diphosphate (7a) and 15-aza-14,15-dihydrogeranylgeranyl thiolodiphosphate (7b)) that exhibit very tight binding. Although arguably not suitable for clinical use, these nevertheless provide a basis for pharmaceutical design against this intriguing biosynthetic pathway. Finally, we provide evidence indicating that this pathway exists only in M. tuberculosis and is not functional in the closely related Mycobacterium bovis because of an inactivating frameshift in the HPS-encoding gene. Thus, we hypothesize that the inability to produce edaxadiene may be a contributing factor in the decreased infectivity and/or virulence of M. bovis relative to M. tuberculosis in humans.

Structure and mechanism of the diterpene cyclase ent-copalyl diphosphate synthase.

Project description:The structure of ent-copalyl diphosphate synthase reveals three α-helical domains (α, β and γ), as also observed in the related diterpene cyclase taxadiene synthase. However, active sites are located at the interface of the βγ domains in ent-copalyl diphosphate synthase but exclusively in the α domain of taxadiene synthase. Modular domain architecture in plant diterpene cyclases enables the evolution of alternative active sites and chemical strategies for catalyzing isoprenoid cyclization reactions.

cis or trans with class II diterpene cyclases.

Project description:Isoprenoid precursors readily undergo (poly)cyclization in electrophilic reaction cascades, presumably as internal addition of the carbon-carbon double-bonds from neighboring isoprenyl repeats readily forms relatively stable cyclohexyl tertiary carbocation intermediates. This hypothesis is agnostic regarding alkene configuration (i.e., Z or E). Consistent with this, here it is shown that certain class II diterpene cyclases, which normally convert (E,E,E)-geranylgeranyl diphosphate to 13E-trans-decalin bicycles, will also act upon (Z,Z,Z)-nerylneryl diphosphate, producing novel 13Z-cis-decalin bicycles instead.

A single residue change leads to a hydroxylated product from the class II diterpene cyclization catalyzed by abietadiene synthase.

Project description:Class II diterpene cyclases catalyze bicyclization of geranylgeranyl diphosphate. While this reaction typically is terminated via methyl deprotonation to yield copalyl diphosphate, in rare cases hydroxylated bicycles are produced instead. Abietadiene synthase is a bifunctional diterpene cyclase that usually produces a copalyl diphosphate intermediate. Here it is shown that substitution of aspartate for a conserved histidine in the class II active site of abietadiene synthase leads to selective production of 8?-hydroxy-CPP instead, demonstrating striking plasticity.

Catalytic Bases and Stereocontrol in Lamiaceae Class II Diterpene Cyclases.

Project description:Plants from the widespread Lamiaceae family produce many labdane-related diterpenoids, a number of which serve medicinal roles, and whose biosynthesis is initiated by class II diterpene cyclases (DTCs). These enzymes utilize a general acid-base catalyzed cyclo-isomerization reaction to produce various stereoisomers of the eponymous labdaenyl carbocation intermediate, which can then undergo rearrangement and/or the addition of water prior to terminating deprotonation. Identification of the pair of residues that cooperatively serve as the catalytic base in the DTCs that produce ent-copalyl diphosphate (CPP) required for gibberellin phytohormone biosynthesis in all vascular plants has led to insight into the addition of water as well as rearrangement. Lamiaceae plants generally contain an additional DTC that produces the enantiomeric normal CPP, as well as others that yield hydroxylated products derived from the addition of water. Here the catalytic base in these DTCs was investigated. Notably, changing two adjacent residues that seem to serve as the catalytic base in the normal CPP synthase from Salvia miltiorrhiza (SmCPS) to the residues found in the closely related perigrinol diphosphate synthase from Marrubium vulgare (MvPPS), which produces a partially rearranged and hydroxylated product derived from the distinct syn stereoisomer of labdaenyl+, altered the product outcome in an unexpected fashion. Specifically, the relevant SmCPS:H315N/T316V double mutant produces terpentedienyl diphosphate, which is derived from complete substituent rearrangement of syn rather than normal labdaenyl+. Accordingly, alteration of the residues that normally serve as the catalytic base surprisingly can impact stereocontrol.

Structure-guided product determination of the bacterial type II diterpene synthase Tpn2.

Project description:A grand challenge in terpene synthase (TS) enzymology is the ability to predict function from protein sequence. Given the limited number of characterized bacterial TSs and significant sequence diversities between them and their eukaryotic counterparts, this is currently impossible. To contribute towards understanding the sequence-structure-function relationships of type II bacterial TSs, we determined the structure of the terpentedienyl diphosphate synthase Tpn2 from Kitasatospora sp. CB02891 by X-ray crystallography and made structure-guided mutants to probe its mechanism. Substitution of a glycine into a basic residue changed the product preference from the clerodane skeleton to a syn-labdane skeleton, resulting in the first syn-labdane identified from a bacterial TS. Understanding how a single residue can dictate the cyclization pattern in Tpn2, along with detailed bioinformatics analysis of bacterial type II TSs, sets the stage for the investigation of the functional scope of bacterial type II TSs and the discovery of novel bacterial terpenoids.

A monodomain class II terpene cyclase assembles complex isoprenoid scaffolds.

Project description:Class II terpene cyclases, such as oxidosqualene and squalene-hopene cyclases, catalyse some of the most complex polycyclization reactions. They minimally exhibit a β,γ-didomain architecture that has been evolutionarily repurposed in a wide range of terpene-processing enzymes and likely resulted from a fusion of unidentified monodomain proteins. Although single domain class I terpene cyclases have already been identified, the corresponding class II counterparts have not been previously reported. Here we present high-resolution X-ray structures of a monodomain class II cyclase, merosterolic acid synthase (MstE). With a minimalistic β-domain architecture, this cyanobacterial enzyme is able to construct four rings in cytotoxic meroterpenoids with a sterol-like topology. The structures with bound substrate, product, and inhibitor provide detailed snapshots of a cyclization mechanism largely governed by residues located in a noncanonical enzyme region. Our results complement the few known class II cyclase crystal structures, while also indicating that archaic monodomain cyclases might have already catalyzed complex reaction cascades.

Discovery, Structure, and Mechanism of a Class II Sesquiterpene Cyclase.

Project description:Terpene cyclases (TCs), extraordinary enzymes that create the structural diversity seen in terpene natural products, are traditionally divided into two classes, class I and class II. Although the structural and mechanistic features of class I TCs are well-known, the corresponding details in class II counterparts have not been fully characterized. Here, we report the genome mining discovery and structural characterization of two class II sesquiterpene cyclases (STCs) from Streptomyces. These drimenyl diphosphate synthases (DMSs) are the first STCs shown to possess β,γ-didomain architecture. High-resolution X-ray crystal structures of DMS from Streptomyces showdoensis (SsDMS) in complex with both a farnesyl diphosphate and Mg2+ unveiled an induced-fit mechanism, with an unprecedented Mg2+ binding mode, finally solving one of the lingering questions in class II TC enzymology. This study supports continued genome mining for novel bacterial TCs and provides new mechanistic insights into canonical class II TCs that will lead to advances in TC engineering and synthetic biology.
