Last name: MALBERT First name: Yannick Title: Flavonoid glucodiversification with engineered sucrose-active enzymes Speciality: Ecological, Veterinary, Agronomic Sciences and Bioengineering, Field: Enzymatic and microbial engineering. Year: 2014 Number of pages: 257 Flavonoid glycosides are natural plant secondary metabolites exhibiting many physicochemical and biological properties. Glycosylation usually improves flavonoid solubility but access to flavonoid glycosides is limited by their low production levels in plants. In this thesis work, the focus was placed on the development of new glucodiversification routes of natural flavonoids by taking advantage of protein engineering. Two biochemically and structurally characterized recombinant transglucosylases, the amylosucrase from Neisseria polysaccharea and the α-(1→2) branching sucrase, a truncated form of the dextransucrase from L. Mesenteroides NRRL B-1299, were selected to attempt glucosylation of different flavonoids, synthesize new α-glucoside derivatives with original patterns of glucosylation and hopefully improved their water-solubility. -

Although many correlations have been described, specific mechanistic links between these changes and glucose homeostasis remain to be defined. Here we show that blood and intestinal levels of the microbiota-produced N-formyl peptide, formyl-methionyl-leucyl-phenylalanine (fMLF), are elevated in high fat diet (HFD)- induced obese mice. Genetic or pharmacological inhibition of the N-formyl peptide receptor Fpr1 leads to increased insulin levels and improved glucose tolerance, dependent upon glucagon- like peptide-1 (GLP-1). Obese Fpr1-knockout (Fpr1-KO) mice also display an altered microbiome, exemplifying the dynamic relationship between host metabolism and microbiota. -
Characterization of Dextransucrase from Leuconostoc Mesenteroides T3, Water Kefir Grains Isolate
Characterization of dextransucrase from Leuconostoc mesenteroides T3, water kefir grains isolate Miona G. Miljković1, Slađana Z. Davidović1, Slavko Kralj2, Slavica S. Šiler-Marinković1, Mirjana D. Rajilić-Stojanović1, Suzana I. Dimitrijević-Branković1 1University of Belgrade, Faculty of Technology and Metallurgy, Department for Biochemical Engineering and Biotechnology, Belgrade, Serbia 2Department for Materials Synthesis, Jožef Stefan Institute, Ljubljana, Slovenia Abstract The production of dextransucrase (DS) by Leuconostoc mesenteroides T3, novel isolate SCIENTIFIC PAPER from water kefir grain, was studied and optimized. Bacterial supernatant reached activity of 3.1 U/ml when the culture was grown at 23 °C and under static culture condition using UDC 63(497.113):632.954:66.061:543 classical Tsuchiya medium for DS production. The increase of sucrose concentration to 7% led to an increase of DS activity by 52% compared to the control. Medium with 2% beef extract and 1% yeast extract resulted in 4.52 U/ml, which was 47% higher than in the Hem. Ind. 71 (4) 351–360 (2017) control (with 2% yeast extract). Finally, the increase of K2HPO4 concentration from 2 to 3% resulted in the increased enzyme activity by 28%. Enzyme purified by polyethylene glycol 400 fractionation displayed maximum activity at 30 °C and pH 5.4. Zymogram analysis confirmed the presence of DS of approximately 180 kDa. The addition of divalent cations Ca2+, Mg2+, Fe2+ and Co2+ led to a minor increase of DS activity, while the addition of Mn2+ was the most prominent with 73% increase. These findings classify dextransucrase from Leuconostoc mesenteroides T3 as promising candidate for production of dextran, which has numerous applications in various industries. -

The amylose was first synthesized by the reaction of SS with ADP [14C] Glc to give ten identical amyloses; the amylopectin was then synthesized by the action of SBE to give ten starches with different amounts of amylopectin. Two of the 14C-amyloses were reacted with 1.0 mIU of purified Starch-Branching-Enzyme (SBE) for 75 and 130 sec, respectively. In a second synthesis, 3 of the amyloses were autoclaved and reacted with 1.0 mIU for 15, 45, and 75 sec. In the third synthesis, 5 amyloses were reacted with different amounts of SBE from 0.50 to 0.01 mIU for 130 sec each. The 10 synthesized starches were separated into amylopectin and amylose fractions. -

Classification Codes in NAPRALERT The NAPRALERT File contains classification codes that designate pharmacological activities. The code and a corresponding textual description are searchable in the /CC field. To be comprehensive, both the code and the text should be searched. Either may be posted, but not both. The following tables list the code and the text for the various categories. The first two digits of the code describe the categories. Each table lists the category described by codes. The last table (starting on page 56) lists the Classification Codes alphabetically. The text is followed by the code that also describes the category. General types of pharmacological activities may encompass several different categories of effect. You may want to search several classification codes, depending upon how general or specific you want the retrievals to be. By reading through the list, you may find several categories related to the information of interest to you. For example, if you are looking for information on diabetes, you might want to included both HYPOGLYCEMIC ACTIVITY/CC and ANTIHYPERGLYCEMIC ACTIVITY/CC and their codes in the search profile.

Pan-Genomic and Transcriptomic Analyses of Leuconostoc
www.nature.com/scientificreports OPEN Pan-genomic and transcriptomic analyses of Leuconostoc mesenteroides provide insights into Received: 8 June 2017 Accepted: 30 August 2017 its genomic and metabolic features Published: xx xx xxxx and roles in kimchi fermentation Byung Hee Chun1, Kyung Hyun Kim1, Hye Hee Jeon1, Se Hee Lee2 & Che Ok Jeon 1 The genomic and metabolic features of Leuconostoc (Leu) mesenteroides were investigated through pan-genomic and transcriptomic analyses. Relatedness analysis of 17 Leu. mesenteroides strains available in GenBank based on 16S rRNA gene sequence, average nucleotide identity, in silico DNA- DNA hybridization, molecular phenotype, and core-genome indicated that Leu. mesenteroides has been separated into diferent phylogenetic lineages. Pan-genome of Leu. mesenteroides strains, consisting of 999 genes in core-genome, 1,432 genes in accessory-genome, and 754 genes in unique genome, and their COG and KEGG analyses showed that Leu. mesenteroides harbors strain-specifcally diverse metabolisms, probably representing high evolutionary genome changes. The reconstruction of fermentative metabolic pathways for Leu. mesenteroides strains showed that Leu. mesenteroides produces various metabolites such as lactate, ethanol, acetate, CO2, mannitol, diacetyl, acetoin, and 2,3-butanediol through an obligate heterolactic fermentation from various carbohydrates. Fermentative metabolic features of Leu. mesenteroides during kimchi fermentation were investigated through transcriptional analyses for the KEGG pathways and reconstructed metabolic pathways of Leu. mesenteroides using kimchi metatranscriptomic data. This was the frst study to investigate the genomic and metabolic features of Leu. mesenteroides through pan-genomic and metatranscriptomic analyses, and may provide insights into its genomic and metabolic features and a better understanding of kimchi fermentations by Leu. -
