Ster, Ian M. "BinK Domain Functional Characterization in the Regulation of Bioluminescence in Vibrio Fischeri." Thesis, University of New Hampshire, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10688468.
Повний текст джерелаProkaryotes encode a remarkable ability to adapt to niches by sensing environmental cues through signal transduction systems (STSs). Typical STS proteins interact through a phosphorylation relay between histidine (His) and aspartate (Asp) residues within modular domains on sensory kinase and response regulator (RR) proteins to elicit cellular responses. A single point mutation in the sensor kinase BinK (BinK1 R537C) conferred an outstanding ability for the non-native V. fischeri strain MJ11 to successfully colonize Euprymna scolopes by affecting multiple symbiotic phenotypes including luminescence activation. However, the role of BinK in luminescence, the interacting partners, and functional mechanism are unknown. We hypothesized that BinK interacts upstream of an orphaned RR and acts as a canonical sensor kinase using a C-terminal receiver (REC) domain to activate luminescence. Heterologous multi-copy expression of BinK in native V. fischeri strain ES114 demonstrated that BinK does not utilize an orphan RR, but instead interfaces with the LuxU-LuxO node to activate luminescence. Additionally, BinK with a truncated REC domain and a REC domain with an aspartate – alanine substitution abolished luminescence activation where the level of light emitted matched the level of light emitted by a strain harboring the empty vector plasmid, suggesting BinK activates luminescence in a REC-dependent manner using the conserved Asp residue for suspected phosphatase / dephosphorylation activity. Elimination of the kinase / auto-phosphorylation activity of the HisKA domain by incorporating a histidine–glutamine substitution did not alter BinK luminescence activation. Though these findings demonstrate one mechanism by which BinK activates luminescence, it is still not clear how the evolved binK1 R537C mutation in the HATPase catalytic domain, a domain important in kinase function, influences REC-dependent dephosphorylation. By using multi-copy expression, BinK1 reduces luminescence and increases qrr1 expression, and like BinK, works in a REC-dependent manner. These data suggest that one way BinK1 conferred the jump to symbiosis was through reduced or altered function. Furthermore, this mutation unveiled BinK as another potential regulator in bioluminescence where it is poised to work in a manner similar to quorum sensing activators AinR and LuxQ to activate luminescence.

Повний текст джерелаCom uma variedade de aplicações potenciais, em diversos campos da ciência, as pesquisas científicas utilizando nanotecnologia são de desenvolvimento relativamente recente. Dentro deste campo de pesquisa, vários novos produtos, com desempenhos melhorados têm sido desenvolvidos. Apesar do aumento de pesquisas sobre a toxicidade dessas tecnologias à biota, o conhecimento sobre esta área ainda é limitado. Visando avaliar a toxicidade e genotoxicidade denanopartículasde sílica (SiNP) no meio ambiente diferentes espécies pertencentes a diversos níveis tróficos (Vibriofisheri, Raphidocelissubcapitata, DaniorerioandAllium cepa) foram expostos a Ludox TM40 (22 nm), Ludox HS30 (12 nm) e Ludox SM30 (7 nm). As espécies de teste foram expostas a concentrações de nanopartículas (NP) variando de 0.29 a 163.8 g/L (TM40) e 0.19 a 122.85 g/L (HS30 e SM30) e os seguintes parâmetros monitorizados durante a exposição: a produção de bioluminescência (V. fischeri), o crescimento taxa (R. subcapitata), inibição de alimentação (D. magna), desenvolvimento embrionário e dano ao DNA (D. rerio) e taxa de germinação, crescimento e danos ao DNA (A. cepa). Nos testes feitos com as SiNPfoi observado que a toxicidade é dependente do tamanho da partícula. O ensaio de bioluminescência apresentou um EC50 de 29.11, 32.34 e 4.58 g/L para TM40, HS30 e SM30, respectivamente. Para o ensaio de taxa de crescimento o EC50 foi 9.32, 9.07 e 7.93 g/Lpara TM40, HS30 e SM30, respectivamente. E para o teste de desenvolvimento embrionário com peixe zebra, para o TM40, HS30 e SM30 o EC50 foi de 5.85, 1.13 e 2.68g/L, respectivamente. Todas as partículas também induziram fitotoxicidade em A. cepa, crescimento e germinação reduziram significativamente quando o organismo foi exposto a SiNP. Efeitos genotóxicos também foram induzir pelas partículas, tanto para A. cepa quanto paraD. rerio. Portanto, as SiNP podem causar toxicidade ao ambiente e o tamanho pode influenciar fortemente a essa toxicidade

Повний текст джерелаPhotodynamic inactivation (PDI) is defined as the process of cell destruction by oxidative stress resulting from the interaction between light and a photosensitizer (PS), in the presence of molecular oxygen. PDI of bacteria has been extensively studied in recent years, proving to be a promising alternative to conventional antimicrobial agents for the treatment of superficial and localized infections. Moreover, the applicability of PDI goes far beyond the clinical field, as its potential use in water disinfection, using PS immobilized on solid supports, is currently under study. The aim of the first part of this work was to study the oxidative modifications in phospholipids, nucleic acids and proteins of Escherichia coli and Staphylococcus warneri, subjected to photodynamic treatment with cationic porphyrins. The aims of the second part of the work were to study the efficiency of PDI in aquaculture water and the influence of different physicalchemical parameters in this process, using the Gram-negative bioluminescent bacterium Vibrio fischeri, and to evaluate the possibility of recycling cationic PS immobilized on magnetic nanoparticles. To study the oxidative changes in membrane phospholipids, a lipidomic approach has been used, combining chromatographic techniques and mass spectrometry. The FOX2 assay was used to determine the concentration of lipid hydroperoxides generated after treatment. The oxidative modifications in the proteins were analyzed by one-dimensional polyacrylamide gel electrophoresis (SDS-PAGE). Changes in the intracellular nucleic acids were analyzed by agarose gel electrophoresis and the concentration of doublestranded DNA was determined by fluorimetry. The oxidative changes of bacterial PDI at the molecular level were analyzed by infrared spectroscopy. In laboratory tests, bacteria (108 CFU mL-1) were irradiated with white light (4.0 mW cm-2) after incubation with the PS (Tri-Py+-Me-PF or Tetra-Py+-Me) at concentrations of 0.5 and 5.0 μM for S. warneri and E. coli, respectively. Bacteria were irradiated with different light doses (up to 9.6 J cm-2 for S. warneri and up to 64.8 J cm-2 for E. coli) and the changes were evaluated throughout the irradiation time. In the study of phospholipids, only the porphyrin Tri-Py+-Me-PF and a light dose of 64.8 J cm-2 were tested. The efficiency of PDI in aquaculture has been evaluated in two different conditions: in buffer solution, varying temperature, pH, salinity and oxygen concentration, and in aquaculture water samples, to reproduce the conditions of PDI in situ. The kinetics of the process was determined in realtime during the experiments by measuring the bioluminescence of V. fischeri (107 CFU mL-1, corresponding to a level of bioluminescence of 105 relative light units). A concentration of 5.0 μM of Tri-Py+-Me-PF was used in the experiments with buffer solution, and 10 to 50 μM in the experiments with aquaculture water. Artificial white light (4.0 mW cm-2) and solar irradiation (40 mW cm-2) were used as light sources.
Os resultados deste trabalho mostraram que E. coli foi totalmente inativada com ambas as porfirinas, enquanto S. warneri foi completamente inativado apenas com a Tri-Py+-Me-PF, ao fim do tempo de irradiação previamente estabelecido. A IF induziu alterações no perfil fosfolipídico bacteriano, com aumento da abundância relativa de algumas das classes maioritárias de fosfolípidos, decréscimo de ácidos gordos insaturados, formação de espécies moleculares oxidadas a partir de ácidos gordos insaturados, nomeadamente nas cardiolipinas de S. warneri e nas fosfatidiletanolaminas de E. coli. Estas espécies oxidadas foram identificadas como derivados hidroxi e hidroperoxi (observados em E. coli) e também grupos carbonilo (em S. warneri). A formação de hidroperóxidos lipídicos confirmou os danos oxidativos nos fosfolípidos. A IF causou redução do conteúdo intracelular dos ácidos nucleicos bacterianos. Em E. coli observou-se a seguinte hierarquia de modificações: rRNA 23S > rRNA 16S > DNA genómico. Os ácidos nucleicos de S. warneri foram extensivamente reduzidos com a Tri-Py+-Me-PF após 5 min de irradiação, mas menos reduzidos com a Tetra-Py+-Me, após 40 min de irradiação. Esta degradação dos ácidos nucleicos ocorreu paralelamente à inativação e quando as células já estavam inativadas mais do que 99.9%. A IF induziu uma diminuição geral do conteúdo proteico de ambas as bactérias, sugerindo degradação em larga escala, ocorrendo as alterações de forma mais rápida e evidente com a porfirina Tri-Py+-Me-PF. Observou-se o aumento da expressão de algumas proteínas, alterações no peso molecular, desaparecimento após tratamento e formação de novas proteínas. As alterações foram associadas a mecanismos de resposta ao stress oxidativo. A espetroscopia de infravermelho mostrou ser um método rápido e económico de avaliar as alterações induzidas pela IF ao nível molecular. Evidenciou os resultados obtidos pelos métodos convencionais com maior detalhe, nomeadamente ao nível das ligações, grupos funcionais e conformações moleculares. As variações de pH (6.5 - 8.5), temperatura (10 - 25 ºC), salinidade (20 - 40 g L-1) e concentração de oxigénio não afetaram significativamente a IF de V. fischeri, uma vez que em todas as condições testadas o sinal bioluminescente diminuiu até ao limite de deteção do método (redução ≈ 7 log10). Os ensaios com água de aquacultura mostraram que a eficiência do processo é afetada pela presença de matéria em suspensão. A IF total de V. fischeri em água de aquacultura foi conseguida com luz solar na presença de 20 μM de Tri-Py+-Me-PF. Os híbridos nanomagnete-porfirina puderam ser reutilizados em 6 ciclos de IF e reciclados em 3 ciclos. Na reciclagem, houve perda de atividade de ciclo para ciclo, atribuída à perda de nanopartículas durante a recuperação. A acumulação de matéria orgânica causou uma redução da eficiência do processo durante a reutilização, contudo foi observada a eliminação de 38 a 42 log10 de bactérias ao fim de 21h30 a 27h de tratamento. O FS não foi fotodegradado e a magnetite das nanopartículas não foi afetada pela irradiação ou pela oxidação inerente ao processo fotodinâmico. O presente trabalho demonstrou o caráter multi-alvo da inativação fotodinâmica, pela elucidação dos mecanismos oxidativos que ocorrem ao nível dos principais constituintes moleculares das bactérias. Também demonstrou que a inativação fotodinâmica é uma metodologia com potencial para ser implementada na desinfeção de águas de aquacultura utilizando fotossensibilizadores imobilizados, permitindo a sua reutilização e reciclagem, com a possibilidade de reduzir os custos associados a este tipo de tratamento.

For the purpose of simplicity, only the regulatory genes, luxR and luxI, were used for studying in this work. A series of gene order rearrangement constructions and in trans comple- mentary tests were designed to investigate the requirement of the sequences of the luxR and luxI genes, and functional analy- sis of the LuxR protein and autoinducer (AI). The luciferase genes, luxA-luxB, from V. harveyi were used as reporter gene to monitor the expression of the R- and L-promoter. The results show that the sequences of the luxR and luxI genes were the ne- gative control elements for the expression of the R- and L-pro- moter. The LuxR-AI complex is the positive control element for both the R- and L-promoter, and directly bound to the R&R se- quence. The sequence of the luxR gene repressed the expression of the L-promoter much stronger than the effect of the sequence of the luxI gene to the R-promoter. Nucleotide sequence analysis showed that an reversed repeat sequence, termed R3- reversed re- peat, was found on the sequence of the luxR gene, and it might be the LuxR motif-binding locus. The site-directed mutagenesis was used to inspect the function of this site. The results of the luxR mutations show that the premature translation of the LuxR protein repressed the expression of the following reporter genes. It suggested that the sequence of the luxR gene might re- gulate the lux regulon by attenuation-like termination. Further modification in this site was be done to define the function of the R3-reversed repeat, but the result can't confirm R3-reversed repeat is LuxR protein motif-binding locus for negative feedback control. The LuxR protein might bind on one specific site of the luxR sequence to enhance the attenuation-like transcriptional termination and negative feedback control the expression of L- operon.
