Under certain environmental conditions, it has massive outbreaks, resulting in attacks of healthy trees, becoming a forest pest. It has been proposed that the bark beetle’s microbiome plays a key role in the insect’s ecology, providing nutrients, inhibiting pathogens, and degrading tree defense compounds, among other probable traits. During a study of bacterial associates from I. typographus, we isolated three strains identified as Pseudomonas from different beetle life stages. In this work, we aimed to reveal the taxonomic status of these bacterial strains and to sequence and annotate their genomes to mine possible traits related to a role within the bark beetle holobiont. -
Structure-Based Virtual Screening of Hypothetical Inhibitors of the Enzyme Longiborneol Synthase—A Potential Target to Reduce Fusarium Head Blight Disease

Stereoselective Synthesis of a 4- -Glucoside of Valienamine and Its X
www.nature.com/scientificreports OPEN Stereoselective synthesis of a 4‑⍺‑glucoside of valienamine and its X‑ray structure in complex with Streptomyces coelicolor GlgE1‑V279S Anshupriya Si1,4, Thilina D. Jayasinghe2,4, Radhika Thanvi1, Sunayana Kapil3, Donald R. Ronning2* & Steven J. Sucheck1* Glycoside hydrolases (GH) are a large family of hydrolytic enzymes found in all domains of life. As such, they control a plethora of normal and pathogenic biological functions. Thus, understanding selective inhibition of GH enzymes at the atomic level can lead to the identifcation of new classes of therapeutics. In these studies, we identifed a 4‑⍺‑glucoside of valienamine (8) as an inhibitor of Streptomyces coelicolor (Sco) GlgE1‑V279S which belongs to the GH13 Carbohydrate Active EnZyme family. The results obtained from the dose–response experiments show that 8 at a concentration of 1000 µM reduced the enzyme activity of Sco GlgE1‑V279S by 65%. The synthetic route to 8 and a closely related 4‑⍺‑glucoside of validamine (7) was achieved starting from readily available D‑maltose. A key step in the synthesis was a chelation‑controlled addition of vinylmagnesium bromide to a maltose‑derived enone intermediate. X‑ray structures of both 7 and 8 in complex with Sco GlgE1‑ V279S were solved to resolutions of 1.75 and 1.83 Å, respectively. Structural analysis revealed the valienamine derivative 8 binds the enzyme in an E2 conformation for the cyclohexene fragment. Also, the cyclohexene fragment shows a new hydrogen‑bonding contact from the pseudo‑diaxial C(3)–OH to the catalytic nucleophile Asp 394 at the enzyme active site. -
Lignite Coal Burning Seam in the Remote Altai Mountains Harbors A

Kadnikov1, Andrey V. Mardanov1, Denis A. Ivasenko2, Dmitry V. Antsiferov2, Alexey V. Beletsky1, Olga V. Karnachuk2 & Nikolay V. Ravin1 Thermal ecosystems associated with underground coal combustion sites are rare and less studied than geothermal features. Here we analysed microbial communities of near-surface ground layer and bituminous substance in an open quarry heated by subsurface coal fre by metagenomic DNA sequencing. Taxonomic classifcation revealed dominance of only a few groups of Firmicutes. Near- complete genomes of three most abundant species, ‘Candidatus Carbobacillus altaicus’ AL32, Brockia lithotrophica AL31, and Hydrogenibacillus schlegelii AL33, were assembled. According to the genomic data, Ca. Carbobacillus altaicus AL32 is an aerobic heterotroph, while B. lithotrophica AL31 is a chemolithotrophic anaerobe assimilating CO2 via the Calvin cycle. H. schlegelii AL33 is an aerobe capable of both growth on organic compounds and carrying out CO2 fxation via the Calvin cycle. Phylogenetic analysis of the large subunit of RuBisCO of B. lithotrophica AL31 and H. schlegelii AL33 showed that it belongs to the type 1-E. All three Firmicutes species can gain energy from aerobic or anaerobic oxidation of molecular hydrogen, produced as a result of underground coal combustion along with other coal gases. We propose that thermophilic Firmicutes, whose spores can spread from their original geothermal habitats over long distances, are the frst colonizers of this recently formed thermal ecosystem. Studies of thermophilic microorganisms that survive and develop at temperatures that are extreme for ordi- nary life have broadened our understanding of the diversity of microorganisms and their evolution, the mech- anisms of adaptation to environmental conditions. -
Product Profiles of Egyptian Henbane Premnaspirodiene
The Journal of Antibiotics (2016) 69, 524–533 & 2016 Japan Antibiotics Research Association All rights reserved 0021-8820/16 www.nature.com/ja ORIGINAL ARTICLE Biosynthetic potential of sesquiterpene synthases: product profiles of Egyptian Henbane premnaspirodiene synthase and related mutants Hyun Jo Koo1,3, Christopher R Vickery1,2,3,YiXu1, Gordon V Louie1, Paul E O'Maille1, Marianne Bowman1, Charisse M Nartey1, Michael D Burkart2 and Joseph P Noel1 The plant terpene synthase (TPS) family is responsible for the biosynthesis of a variety of terpenoid natural products possessing diverse biological functions. TPSs catalyze the ionization and, most commonly, rearrangement and cyclization of prenyl diphosphate substrates, forming linear and cyclic hydrocarbons. Moreover, a single TPS often produces several minor products in addition to a dominant product. We characterized the catalytic profiles of Hyoscyamus muticus premnaspirodiene synthase (HPS) and compared it with the profile of a closely related TPS, Nicotiana tabacum 5-epi-aristolochene synthase (TEAS). The profiles of two previously studied HPS and TEAS mutants, each containing nine interconverting mutations, dubbed HPS-M9 and TEAS- M9, were also characterized. All four TPSs were compared under varying temperature and pH conditions. In addition, we solved the X-ray crystal structures of TEAS and a TEAS quadruple mutant complexed with substrate and products to gain insight into the enzymatic features modulating product formation. These informative structures, along with product profiles, -

The shikimate pathway is of pivotal importance for production of a plethora of aromatic compounds in plants, bacteria, and fungi. Putative structural differences in the enzymes from the shikimate pathway, between the proteins of bacterial origin and those of plants, could be used for the development of a drug for the control of CVC. However, inhibitors for shikimate pathway enzymes should have high specificity for X. fastidiosa enzymes, since they are also present in plants. -
