2. Protein-protein interactions of the nicotinamide/nicotinate mononucleotide adenylyltransferase of Leishmania braziliensis
BACKGROUND Nicotinamide adenine dinucleotide (NAD) plays a central role in energy metabolism and integrates cellular metabolism with signalling and gene expression. NAD biosynthesis depends on the enzyme nicotinamide/nicotinate mononucleotide adenylyltransferase (NMNAT; EC: 2.7.7.1/18), in which converge the de novo and salvage pathways. OBJECTIVE The pu

3. GJB2 c.235delC variant associated with autosomal recessive nonsyndromic hearing loss and auditory neuropathy spectrum disorder
Abstract Autosomal recessive nonsyndromic hearing loss (ARNSHL) is a genetically heterogeneous neurosensory disorder, usually characterized by congenital or prelingual hearing loss. We report a Han Chinese male, born to consanguineous parents, presenting with nonsyndromic sensorineural hearing loss, whose clinical phenotype was also consistent with auditory

4. Application of n-dodecane as an oxygen vector to enhance the activity of fumarase in recombinant Escherichia coli: role of intracellular microenvironment
Abstract The effect of the intracellular microenvironment in the presence of an oxygen vector during expression of a fusion protein in Escherichia coli was studied. Three organic solutions at different concentration were chosen as oxygen vectors for fumarase expression. The addition of n-dodecane did not induce a significant change in the expression of fumar

5. Molecular cloning, characterization and expression analysis of a novel PDRG1 gene from black tiger shrimp (Penaeus monodon)
Abstract P53 And DNA Damage-Regulated Gene 1 (PDRG1) is a novel gene which plays an important role in chaperone-mediated protein folding. In the present study, the full-length complementary DNA (cDNA) sequence of the PDRG1 gene from Penaeus monodon (PmPDRG1) was cloned by the rapid amplification of cDNA ends (RACE) method. The cDNA of PmPDRG1 spans 1,613 bp,

6. Heterologous expression, protein folding and antibody recognition of a neurotoxin from the Mexican coral snake Micrurus laticorallis
Abstract Background The cysteine-rich neurotoxins from elapid venoms are primarily responsible for human and animal envenomation; however, their low concentration in the venom may hamper the production of efficient elapid antivenoms. Therefore, the aim of the present study was to produce fully active elapid neurotoxic immunogens for elapid antivenom produc

7. Phylogenetic analysis of Dengue virus 1 isolated from South Minas Gerais, Brazil
Abstract Dengue is a major worldwide public health problem, especially in the tropical and subtropical regions of the world. Primary infection with a single Dengue virus serotype causes a mild, self-limiting febrile illness called dengue fever. However, a subset of patients who experience secondary infection with a different serotype can progress to a more s

8. A comparison between the recombinant expression and chemical synthesis of a short cysteine-rich insecticidal spider peptide
Abstract Background: The choice between heterologous expression versus chemical synthesis for synthesizing short cysteine-rich insecticidal peptides from arthropods may impact the obtainment of yields and well-folded bioactive molecules for scientific research. Therefore, two recombinant expression systems were compared to

9. Myoglobin entrapment in poly(vinyl alcohol) dense membranes
Our goal in this study was the immobilization of myoglobin in poly(vinyl alcohol) dense membranes. Glutaraldehyde was investigated both as the crosslinking agent, aiming to increase the membrane stability in aqueous medium, and as the vehicle to bind myoglobin and PVA. Reaction and membrane synthesis were carried simultaneously in mild operating conditions i

10. Influência do Gene pacC na Regulação de Manosiltransferases no Dermatófito Trichophyton rubrum em Função de Variações Nutricionais e pH Ambiente. / Influence of Gene pacC in Mannosiltransferase Regulation of the Dermathophyte Trichophyton rubrum in Function to Changes by pH and Nutrient Sources.
Gene expression regulation is essential for fungi to adapt to environmental adversities, such as changes in the extracellular pH, nutrient starvation, ionic strength, and temperature. The adaptive response to ambient pH is well characterized in model fungi such as Aspergillus nidulans, and involves the signal transduction pathway consisting of the products o

As bactérias patogênicas gram-negativas desenvolveram estratégias sofisticadas para infectar seus hospedeiros, utilizando sistemas de secreção especializados para translocar proteínas de virulência através da membrana das células eucarióticas para o citoplasma. Para que este processo seja eficiente, estas proteínas de virulência devem estar parci

12. Uso de Data Mining na descoberta ou identificação de regras de enovelamento baseado em perfis de hidrofobicidade / Use of Data Mining in the discovery or identification of folding rules based on hydrophobicity profiles
As proteínas são moléculas complexas encontradas em células vivas. Elas possuem uma estrutura terciária (tridimensional) específica que determina sua função e é necessária para a ligação específica de substratos ou outros ligantes. A estrutura de uma proteína pode ser organizada em quatro níveis hierárquicos: estrutura primária (sequência d
