Enzymatic Biosynthesis of Vomilenine, a Key Intermediate of the Ajmaline Pathway, Catalyzed by a Novel Cytochrome P 450-Dependent Enzyme from Plant Cell Cultures of Rauwolfia serpentina Heike Falkenhagen and Joachim Stöckigt Lehrstuhl für Pharmazeutische Biologie der Johannes Gutenberg-Universität Mainz, Institut für Pharmazie, Staudinger Weg 5, D-55099 Mainz, Bundesrepublik Deutschland Z. Naturforsch. 50c, 45-53 (1995); received September 26, 1994 Vomilenine, Vinorine, Vinorine Hydroxylase, Cytochrome P450, Rauwolfia serpentina Microsomal preparations from Rauwolfia serpentina Benth. cell suspension cultures cata lyze a key step in the biosynthesis of ajmaline - the enzymatic hydroxylation of the indole alkaloid vinorine at the allylic C-21 resulting in vomilenine. Vomilenine is an important branch-point intermediate, leading not only to ajmaline but also to several side reactions of the biosynthetic pathway to ajmaline. The investigation of the taxonomical distribution of the enzyme indicated that vinorine hydroxylase is exclusively present in ajmaline-producing plant cells. The novel enzyme is strictly dependent on NADPH2 and 0 2 and can be inhibited by typical cytochrome P450 inhibitors such as cytochrome c, ketoconazole and carbon mon oxide (the effect of CO is reversible with light of 450 nm). This suggests that vinorine hy droxylase is a cytochrome P450-dependent monooxygenase. A pH optimum of 8.3 and a temperature optimum of 40 °C were found. The Km value was 3 for NADPH2 and 26 [i,M for vinorine. The optimum enzyme activity could be determined at day 4 after inoculation of the cell cultures in AP I medium. Vinorine hydroxylase could be stored with 20% sucrose at -28 °C without significant loss of activity. -

Evolutionary Routes to Biochemical Innovation Revealed by Integrative
RESEARCH ARTICLE Evolutionary routes to biochemical innovation revealed by integrative analysis of a plant-defense related specialized metabolic pathway Gaurav D Moghe1†, Bryan J Leong1,2, Steven M Hurney1,3, A Daniel Jones1,3, Robert L Last1,2* 1Department of Biochemistry and Molecular Biology, Michigan State University, East Lansing, United States; 2Department of Plant Biology, Michigan State University, East Lansing, United States; 3Department of Chemistry, Michigan State University, East Lansing, United States Abstract The diversity of life on Earth is a result of continual innovations in molecular networks influencing morphology and physiology. Plant specialized metabolism produces hundreds of thousands of compounds, offering striking examples of these innovations. To understand how this novelty is generated, we investigated the evolution of the Solanaceae family-specific, trichome- localized acylsugar biosynthetic pathway using a combination of mass spectrometry, RNA-seq, enzyme assays, RNAi and phylogenomics in different non-model species. Our results reveal hundreds of acylsugars produced across the Solanaceae family and even within a single plant, built on simple sugar cores. The relatively short biosynthetic pathway experienced repeated cycles of *For correspondence: [email protected] innovation over the last 100 million years that include gene duplication and divergence, gene loss, evolution of substrate preference and promiscuity.

3D-Structure of Vinorine Synthase from Rauvolfia Serpentina in Complex with Its Ligand Acetyl-Coa
3D-Structure of Vinorine Synthase from Rauvolfia serpentina in Complex with its Ligand Acetyl-CoA M. Hill, S. Panjikar1, X. Ma, J. Stöckigt Department of Pharmaceutical Biology, Institute of Pharmacy, Johannes Gutenberg-University Mainz, Staudingerweg 5, D-55099 Mainz, Germany 1EMBL Hamburg outstation DESY, Notkestraße 85, D-22607 Hamburg, Germany Vinorine synthase (VS, EC 2.3.1.160) is an acetyl transferase that occupies a central role in the biosynthesis of the antiarrhythmic monoterpenoid indole alkaloid ajmaline in the Indian medicinal plant Rauvolfia serpentina. The enzyme catalyzes the reversible acetyl-CoA dependent formation of the ajmalan-type alkaloid vinorine from the sarpagine-type alkaloid 16-epi-vellosimine (Fig. 1) [1]. VS belongs to the BAHD (benzylalcohol acetyl-, anthocyanin-O-hydroxy-cinnamoyl, anthranilate-N-hydroxy-cinnamoyl/benzoyl-, deacetylvindoline acetyltransferase) enzyme superfamily of acetyl transferases, which members are involved in biosynthesis of several important drugs (morphine, taxol, vincaleucoblastine and vincristine) and other products of secondary metabolism in plants. The synthase consists of 412 amino acids and has a molecular weight of 46.8 kDa. All conserved residues typical for the BAHD family are found in VS. Prominent features of this family are the HxxxD motif in the active site and the DFGWG motif near the C-terminus. The typical low overall sequence identity (25-34%) to other BAHD members might indicate a divergent evolution of the family from one ancestral gene [2].

Complete Genome Sequencing and Antibiotics Biosynthesis Pathways
www.nature.com/scientificreports OPEN Complete genome sequencing and antibiotics biosynthesis pathways analysis of Streptomyces lydicus Received: 14 December 2016 Accepted: 13 February 2017 103 Published: 20 March 2017 Nan Jia1,2, Ming-Zhu Ding1,2, Hao Luo1,2,3, Feng Gao1,2,3 & Ying-Jin Yuan1,2 More and more new natural products have been found in Streptomyces species, which become the significant resource for antibiotics production. Among them,Streptomyces lydicus has been known as its ability of streptolydigin biosynthesis. Herein, we present the genome analysis of S. lydicus based on the complete genome sequencing. The circular chromosome of S. lydicus 103 comprises 8,201,357 base pairs with average GC content 72.22%. With the aid of KEGG analysis, we found that S. lydicus 103 can transfer propanoate to succinate, glutamine or glutamate to 2-oxoglutarate, CO2 and L-glutamate to ammonia, which are conducive to the the supply of amino acids. S. lydicus 103 encodes acyl-CoA thioesterase II that takes part in biosynthesis of unsaturated fatty acids, and harbors the complete biosynthesis pathways of lysine, valine, leucine, phenylalanine, tyrosine and isoleucine. Furthermore, a total of 27 putative gene clusters have been predicted to be involved in secondary metabolism, including biosynthesis of streptolydigin, erythromycin, mannopeptimycin, ectoine and desferrioxamine B. Comparative genome analysis of S. lydicus 103 will help us deeply understand its metabolic pathways, which is essential for enhancing the antibiotic production through metabolic engineering. Streptomyces species are high-GC Gram-positive bacteria found predominantly in soil1. Through a complex pro- cess of morphological and physiological differentiation, Streptomyces species could produce many specialized metabolites used for agricultural antibiotics2. -
Properties of Vinorine Synthase — the Rauwolfia Enzyme Involved in the Formation of the Ajmaline Skeleton
Properties of Vinorine Synthase — the Rauwolfia Enzyme Involved in the Formation of the Ajmaline Skeleton Artur Pfitzner, Leo Polz, and Joachim Stöckigt Institut für Pharmazeutische Biologie der Ludwig Maximilians Universität München, Karlstr. 29, D-8000 München 2, Bundesrepublik Deutschland Z. Naturforsch. 41c, 103—114 (1986); received July 3. 1985 Dedicated to Professor Hans Grisebach on the occasion of his 60th birthday Rauwolfia serpentina Benth., Cell Suspension Cultures, Vinorine Synthase, Ajmaline Skeleton Vinorine synthase, a key enzyme in the formation of the Rauwolfia alkaloid ajmaline and its derivatives, has been isolated from Rauwolfia serpentina cell suspension cultures. The new enzy me has been 160-fold purified and characterized in detail. The synthase catalyses a single step in the biosynthesis of ajmalan alkaloids by the acetyl-coenzyme A and 16-epi-vellosimine dependent formation of vinorine, which shows the basic ajmaline skeleton. Besides a characteristic substrate specificity the major properties of the enzyme are a relatively high pH optimum (pH 8.5), a temperature optimum of 35 °C, an isoelectric point of pH 4.4, and a relative molecular weight of 31000 ± 8%. The apparent K m values for 16-epi-vellosimine and acetyl-coenzyme A were 19.4 [xm and 64 |xm resp. for the formation of vinorine. Kinetic data of the catalysed reaction indicate that 17-deacetylvinorine is not involved as a free intermediate during the vinorine biosyn thesis. Vinorine was proved by in vivo feeding experiments to be the biosynthetic precursor of the alkaloids in the final stages of the ajmaline pathway, vomilenine (21-hydroxyvinorine), 17-0- acetylnorajmaline and 17-O-acetylajmaline. -

Identification and Characterization of Piperine Synthase from Black
ARTICLE https://doi.org/10.1038/s42003-021-01967-9 OPEN Identification and characterization of piperine synthase from black pepper, Piper nigrum L. Arianne Schnabel 1, Benedikt Athmer1, Kerstin Manke1, Frank Schumacher2, Fernando Cotinguiba 3 & ✉ Thomas Vogt 1 Black pepper (Piper nigrum L.) is the world’s most popular spice and is also used as an ingredient in traditional medicine. Its pungent perception is due to the interaction of its major compound, piperine (1-piperoyl-piperidine) with the human TRPV-1 or vanilloid receptor. We now identify the hitherto concealed enzymatic formation of piperine from piperoyl coenzyme A and piperidine based on a differential RNA-Seq approach from developing black pepper 1234567890():,; fruits. This enzyme is described as piperine synthase (piperoyl-CoA:piperidine piperoyl transferase) and is a member of the BAHD-type of acyltransferases encoded by a gene that is preferentially expressed in immature fruits. A second BAHD-type enzyme, also highly expressed in immature black pepper fruits, has a rather promiscuous substrate specificity, combining diverse CoA-esters with aliphatic and aromatic amines with similar efficiencies, and was termed piperamide synthase. Recombinant piperine and piperamide synthases are members of a small gene family in black pepper. They can be used to facilitate the microbial production of a broad range of medicinally relevant aliphatic and aromatic piperamides based on a wide array of CoA-donors and amine-derived acceptors, offering widespread applications. 1 Leibniz Institute of Plant Biochemistry, Dept.
