MODY2 or GCK-MODY is caused by inactivating heterozygous mutations in the glucokinase. Linkage of MODY to the Arg85Trp GCK mutation, among Algerian diabetic patients has been established in our previous research. The main objective of this study is to strengthen the evidence for the pathogenicity of this mutation using bioinformatics tools. For this purpose, prediction of Arg85Trp mutation effect on glucokinase (PDB ID: 1V4T) stability was performed using I-Mutant 3.0, PoPMuSiC 3.1, DUET and mCSM web servers. Otherwise, structural analysis was performed after optimization of the native and the mutated structures (PDB ID: 1V4T). For that the steepest descent geometries optimization were applied using Nano Molecular Dynamics software (NAMD 2.12). Subsequently, interactions established between the native Arg85 or the mutated Trp85 and the surrounding residues were studied using Accelrys Discovery Studio Visualizer software. In silico analysis conducted through I-Mutant 3.0, PoPMuSiC 3.1, DUET and mCSM softwares, predicts the Arg85Trp as a destabilizing mutation. Structural modeling gives further evidence in favor of the pathogenicity of this mutation. Overall, our results corroborate with the previous metabolic and in silico studies which associate Arg85Trp mutation to MODY phenotype.","PeriodicalId":11025,"journal":{"name":"Current Research in Bioinformatics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84472112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is in this context that the present work falls. It concerns the isolation, characterization and identification of local bacterial strains for the purpose of their use in the control of certain pests. Indeed, 20 bacteria were isolated from soil cultivated in the region of Boumerdes (center of Algeria) with a total of 21 bacterial strains isolated from Adrar region (Desert Algerian). After carrying out the efficacy tests against 2 insect pests; Migratory locust (Locusta migratoria) and wax moth (Galleria mellonella), 8 potentially interesting strains were identified based on their genetic traits. Molecular characterization of these strains was performed by isolation of DNA, PCR and sequencing of the 16S rRNA gene, followed by phylogenetic analysis. The rDNA16S sequences of the 8 strains named B1, B2, B3, B4, B5, B6, H1 and H2 were recorded in the EMBL/EBI database and their phylogenetic analysis revealed that they belong to the genera Bacillus, Pseudomonas, Enterobacter and Delftia with a very high percentage of similarity with Bacillus thuringiensis strains (NR_043403) (99%) for isolate B1, Bacillus weihenstephanensis (NR_024697) (99%) for isolate B2, Pseudomonas fragi (JCM5420) (99%) for isolates B3 and B4, Bacillus thuringiensis (CMBLBT-5) (99%) for isolate B4, Enterobacter ludwigii (EN-119) for B5, Bacillus thuringiensis (4916) (99%) for isolate H1 and Delftia lacustris (R-54734) (100%) for isolate H2.","PeriodicalId":11025,"journal":{"name":"Current Research in Bioinformatics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77088250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The molecular docking was carried out using Molecular Operating Environment (MOE) software package. Docking analysis showed that this compounds (perilladehyde and D-limonene) can interact with both the Catalytic Active Site (CAS) of AChE, BuChE and MAO. For D-limonene, molecular docking showed favorable H-phi interaction with catalytic residue of AchE and BuChE. The perillaldehyde showed best interaction profile with BuChE as compared with compound D-Limonene. The best interaction between perilladehyde and monoamine oxidase was also revealed.

This gene is located in position 17q21,32 and consists of 11 exons. The characterization and understanding of genetic variation is a real challenge in human genetics, both for healthy individuals and diseased ones. The in silico study of the B4GALNT2 gene’s polymorphism using a bioinformatic methodology by means of analyzing various databases and open source web browsers has shown that this gene is characterized by a polymorphic profile that has a very large number of Cosmic SNPs associated with different types of cancer. The prediction of the 3D structure in silico is an important step to better understand the overall architecture of the B4GALNT2 protein. The chosen model this study is one of chondroitin synthase with a recovery percentage of 20.10% relative to the target sequence. Our findings suggest that these cosmic polymorphisms are at the origin of a cellular disorder responsible for the initiation, birth and proliferation of tumors. Bioinformatics has become an indispensable tool in identifying and predicting the function of the B4GALNT2 gene and its relation to cancer.","PeriodicalId":11025,"journal":{"name":"Current Research in Bioinformatics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74923203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study of this microflora revealed the presence of a significant morphological, physiological and metabolic diversity.

The results showed that these isolates were related to the genera Haloferax (for the strain ATS1) and Halomonas (strains A1, A2 and A4), Staphylococcus (strain A3), Salinivibrio (strain B1), Planococcus (strain B4) and Halobacillus (strain B5).
