Abstract:

Background A large proportion of an organism's genome encodes for membrane proteins. Membrane proteins are important for many cellular processes, and several diseases can be linked to mutations in them. With the tremendous growth of sequence data, there is an increasing need to reliably identify membrane proteins from sequence, to functionally annotate them, and to correctly predict their topology. Results We introduce a technique called structural fragment clustering, which learns sequential motifs from 3D structural fragments. From over 500,000 fragments, we obtain 213 statistically signifi

Abstract:

While the advances of the scientific community have enabled extraordinary improvements in the capabilities of synthetic biology, there is a continued desire in biotechnology for enhanced or entirely novel biological functions. As proteins are either directly or indirectly responsible for the vast majority of naturally occurring biological activities, the modification of peptide structures constitutes a promising approach to address the ambitions of biotechnology. Central to the work in this thesis is the recognition that naturally occurring protein structures are intangibly complex due to the

Abstract:

The unicellular yeast, Pichia pastoris has currently emerged as one of the most popular host systems for heterologous proteins due to its relatively cheap cost, easy genetic manipulability, ability to perform post-translational modifications on proteins, and respiratory growth capabilities which allow it to be cultured in very high concentrations. Over 700 foreign proteins have been recombinantly expressed using P. pastoris. Although P. pastoris appears to be an ideal host system, its main drawback is its inability to efficiently export some heterologous proteins into the extracellular medium.

Abstract:

Being able to control protein function directly and in real time is attractive. In this thesis, I discuss controlling protein activity using alternating current electric fields on the order of 1 MV/m. Since protein structures result in localized and/or protein-wide charge gradients, it is expected that a sufficiently high electric field applied across a protein should result in structural distortions which can temporarily alter or halt protein function. The field is set to oscillate above the influences of the electrochemical double layer effects (1 kHz) and below the level needed for hydrodyn

The ability of members of the hsp70 family to bind to peptides in vivo and in vitro suggests that they may be involved in the processing of antigens for binding to Major Histocompatibility (MHC) class I and/or class n molecules. The aims of this thesis have been to provide evidence for the involvement of hsp70s in antigen processing and to characterise the binding of peptides by hspTOs by structural and functional studies. Firstly, the peptide-binding domains of two hsp70s, hsp70hom and PBP74, were expressed in isolation from the rest of the molecule for structure determination. Both of these

Abstract:

The methylotrophic yeast. Pichia pastoris, is a powerful, adaptable, and inexpensive recombinant expression system commonly used to secrete heterologous protein. Although P. pastoris is a popular host organism, secretion inefficiency continues to be a major hurdle in its ability to produce high levels of foreign protein. Optimization of cis- and trans-acting factors has greatly enhanced the secretory capabilities of P. pastoris, however protein-specific engineering of a host organism is costly and not always effective. P. pastoris' secretion inefficiency is commonly due to trans-acting factors

A demana de proteases no mercado brasileiro promove pesquisas como também o empreendorismo nesse segmento embora mais investimentos por parte das agências do governo devem ser necessárias.

Abstract:

Conselho Nacional de Desenvolvimento Científico e Tecnológico<br>As refinarias de petróleo, assim como outros processos industriais em grande escala, são fontes potenciais de poluição ambiental. Os acidentes ocorridos com derramamento de petróleo e seus derivados no Brasil, no período de 1975 a 2012, somam milhões de litros de poluentes que promoveram a contaminação de solos, rios e mar. Os processos fisíco-químicos tais como, a centrifugação, ultrafiltração e flotação por ar dissolvido (FAD), podem ser eficazes quando usados para separar óleos emulsionados. Nesse sentido, o processo de FAD co

Abstract:

Spider silk is renowned for its extraordinary mechanical properties, having a balance of high tensile strength and extensibility. To date, the majority of studies have focused on the production of dragline silks from synthetic spider silk gene products. Here we report the first mechanical analysis of synthetic egg case silk fibers spun from the Latrodectus hesperus tubuliform silk proteins, TuSp1 and ECP-2. We provide evidence that recombinant ECP-2 proteins can be spun into fibers that display mechanical properties similar to other synthetic spider silks. We also demonstrate that silks spun f

O sequenciamento genômico da L. interrogans sorovar Copenhageni e ferramentas de bioinformática nos permitiram selecionar 15 genes que codificam proteínas hipotéticas conservadas preditas de superfície. A conservação foi confirmada por PCR em seis dos sorovares mais predominantes de L. interrogans. As proteínas recombinantes foram clonadas em vetor de expressão de E. coli em fusão com seis resíduos de histidina, que permite a purificação por cromatografia de afinidade a metal. Seis proteínas apresentaram reatividade com anticorpos presentes em soros de pacientes com leptospirose. Através de um

Abstract:

Uma característica associada à capacidade de Pseudomonas aeruginosa sobreviver e disseminar-se frente a situações adversas encontradas no ambiente e no organismo de hospedeiros é a regulação de genes de resposta a condições de estresse celular, que incluem o evento de choque térmico. A exposição do microrganismo a um ambiente de alta temperatura resulta na indução da síntese de proteínas específicas, representadas por chaperonas e proteases, que conferem um aumento da viabilidade celular microbiana em condições consideradas letais.

Abstract:

Our increasing understanding of disease mechanisms coupled with technological advances has facilitated the generation of pharmaceutical proteins, which are able to address yet unmet medical needs. Diseases that were fatal in the past can now be treated with novel biological medications improving and prolonging life for many patients. Pharmaceutical protein production is, however, a complex undertaking, which is by no means problem-free. The demand for more complex proteins and the realization of the importance of post-translational modifications have led to an increasing use of mammalian cells

Dissertation (PhD)--University of Stellenbosch, 2007.<br>ENGLISH ABSTRACT: Plants have developed sophisticated means of combating plant diseases. The events that prepare the plant for, and follow plant-pathogenic interactions, are extremely complex and have been the topic of intensive investigation in recent years. These interactions involve a plethora of genes and proteins, and intricate regulation thereof; from the host and pathogen alike. Studying the contribution of single genes and their encoded proteins to the molecular dialogue between plant and pathogen has been a focus of plant
