| Proteases hydrolyze the peptide bonds of proteins into peptides and amino acids, being found in all living organisms, and are essential for cell growth and differentiation. Proteolytic enzymes have potential application in a wide number of industrial processes such as food, laundry detergent and pharmaceutical. Proteases from microbial sources have dominated applications in industrial sectors. Fungal proteases are used for hydrolyzing protein and other components of soy beans and wheat in soy sauce production. Proteases can be produced in large quantities in a short time by established methods of fermentation. The parameters such as variation in C/N ratio, presence of some sugars, besides several other physical factors are important in the development of... |

| Tellurium is a rare element which has been regarded as a toxic, non-essential trace element and its biological role is not clearly established to date. Besides of that, the biological effects of elemental tellurium and some of its inorganic and organic derivatives have been studied, leading to a set of interesting and promising applications. As an example, it can be highlighted the uses of alkali-metal tellurites and tellurates in microbiology, the antioxidant effects of organotellurides and diorganoditellurides and the immunomodulatory effects of the non-toxic inorganic tellurane, named AS-101, and the plethora of its uses. Inasmuch, the nascent applications of organic telluranes (organotelluranes) as protease inhibitors and its applications in disease... |

| Background: Enzymes belonging to the same super family of proteins in general operate on variety of substrates and are inhibited by wide selection of inhibitors. In this work our main objective was to expand the scope of studies that consider only the catalytic and binding pocket amino acids while analyzing enzyme specificity and instead, include a wider category which we have named the Interface Forming Residues (IFR). We were motivated to identify those amino acids with decreased accessibility to solvent after docking of different types of inhibitors to sub classes of serine proteases and then create a table (matrix) of all amino acid positions at the interface as well as their respective occupancies. Our goal is to establish a platform for analysis of... |

| Cigarrinhas são as principais pragas da pastagem e da cana-de-açúcar, destacando-se os gêneros Deois e Mahanarva. Essas pragas vêm causando sérios danos a estas culturas na região de Tangará da Serra, MT, Brasil. O fungo Metarhizium anisopliae é considerado um eficiente agente para o controle biológico de insetos, possuindo vários fatores de virulência, incluindo a produção de proteases, consideradas fundamentais no processo de penetração através da cutícula do inseto. Este trabalho tem como objetivos analisar a produção de proteases extracelulares a partir de isolados de M. anisopliae, utilizando substratos cuticulares e não-cuticulares, e verificar a influência desses substratos na expressão dessas enzimas. Foram utilizados 4 isolados de M. anisopliae... |

| ABSTRACT Wolf cichlid, Parachromis dovii, is a species with a high potential for aquaculture in Central America; however, the knowledge of the digestive physiology in larvae period is limited. For these reason, this study evaluated the changes on digestive enzymes (alkaline and acid proteases, trypsin, chymotrypsin, aminopeptidase, carboxypeptidase, lipases, amylases, and phosphatases) during early ontogeny by biochemical analysis. All digestive enzymes were detected at first feeding (6 days after hatching, DAH, 9.49 mm, 168 degree-days DD). Afterwards all enzymes reached two main peaks in activity at 14 or 22 DAH (15.10 mm, 364 DD and 20.83 mm, 550 DD, respectively). Later, there was a gradual decrease in activity for trypsin and acid and alkaline... |

| ABSTRACT In the Southeast of Mexico, there are many native cichlids with commercial interest such as redhead cichlid (Vieja melanurus) and twoband cichlid (V. bifasciata), which have a great local demand and excellent meat quality. However, it is necessary to implement their culture based on nutrition studies and digestive biochemistry. This study’s objective was to characterize these two cichlids’ digestive proteases (pH, temperature, and inhibitors) through biochemistry techniques. Results showed that V. melanurus and V. bifasciata have a digestive capacity analogous to other omnivore fishes, where the optimal pH values of stomach proteases (4 and 2, respectively) and intestinal proteases (6 and 12, respectively), the optimal temperature of acid (35°C... |

| Mycoplasmas are very fastidious in their nutritional requirements for in vitro growth and have limited biosynthetic capacity, a reflection of their reduced genomes. As a result, these bacteria depend upon external metabolites for nutrition and growth and have developed dependence on their hosts for survival and maintenance. Protein degradation and peptide importation play an important role in Mycoplasma spp. nutrition, and proteases can play a role in host adaptation and pathogenicity. Here, we present a general survey on the genes involved in protein degradation, secretion and importation, comparing all available Mollicute genomes. |

| RESUMO - Com os objetivos de quantificar, isolar e caracterizar bactérias psicrotróficas contaminantes de leite cru refrigerado, produzido na região da Zona da Mata de Minas Gerais e Sudeste do Rio de Janeiro, foram analisadas amostras de leite coletadas de 20 tanques coletivos e 23 tanques individuais. As contagens de bactérias psicrotróficas nas amostras de leite para os dois tipos de tanques de refrigeração variaram entre 102 e 107 Unidades Formadoras de Colônias (UFC) ml-1, porém, um maior número de tanques coletivos apresentou contagens acima de 1 x 105 UFC ml-1. Foi verificada a predominância de bactérias psicrotróficas gram-negativas (81,2%), que foram identificadas pelos sistemas API 20E e API 20NE nos gêneros: Aeromonas, Alcaligenes,... |

| Vegetais são uma rica fonte de proteínas bioativas de amplo interesse e variadas aplicações. Proteases, peroxidases e inibidores de proteases são foco de diversas pesquisas no intuito de investigar a funcionalidade e uso dessas biomoléculas em diversas áreas. Proteases cisteínicas são importantes para o desenvolvimento das plantas, participando em processos como a mobilização de proteínas de reserva, senescência e morte celular programada (HAQ, 2004). Peroxidases ocorrem amplamente em vegetais e estão envolvidas em vários processos do metabolismo, podendo ser empregadas na construção de biosensores e em muitos processos industriais (FATIBELO e VIEIRA, 2002). Proteínas inibidoras de proteases são moléculas que inibem a atividade de enzimas proteolíticas... |
