1. Classic and current concepts in adrenal steroidogenesis: a reappraisal
ABSTRACT Adrenal steroid biosynthesis and its related pathology are constant evolving disciplines. In this paper, we review classic and current concepts of adrenal steroidogenesis, plus control mechanisms of steroid pathways, distribution of unique enzymes and cofactors, and major steroid families. We highlight the presence of a “mineralocorticoid (MC) pat

2. Phenotypic Characterization and Synthesis of Extracellular Catecholase from a Newly Isolated Bacterium Pseudomonas sp. BSC-6
Abstract Catecholase (EC 1.10.3.1), an oxidoreductase enzyme is a key member of polyphenol oxidase family which catalyze the degradation of catechol. This enzyme possesses vast applications in diverse areas and is found in bacteria, fungi, mushrooms, higher plants, arthropods, amphibians and mammals. Catechol, a phenolic compound, is used as a starting mate

3. Nrf2, NF-κB and PPARβ/δ mRNA Expression Profile in Patients with Coronary Artery Disease
Resumo Fundamentos: O estresse oxidativo e a inflamação estão presentes na doença arterial coronariana (DAC) e estão ligados à ativação do fator de transcrição nuclear kappa B (NF-κB). Para atenuar essas complicações, fatores de transcrição como o fator nuclear eritroide 2-relacionado ao fator 2 (Nrf2) e o receptor ativado por proliferador de

4. BIOPRODUCTION AND CHARACTERIZATION OF SODIUM, POTASSIUM, AND CALCIUM LACTOBIONATES
Lactobionic acid and its salts are substances that have several applications in the pharmaceutical area. These products were obtained by bioconversion through the enzymatic complex glucose-fructose-oxidoreductase (GFOR)/gluconolactonase (GL) present in calcium alginate immobilized cells of Zymomonas mobilis. In the reactions catalyzed by this enzyme system,

5. Long-term follow-up of a female with congenital adrenal hyperplasia due to P450-oxidoreductase deficiency
SUMMARY P450 oxidoreductase deficiency (PORD) is a variant of congenital adrenal hyperplasia that is caused by POR gene mutations. The POR gene encodes a flavor protein that transfers electrons from nicotinamide adenine dinucleotide phosphate (NADPH) to all microsomal cytochrome P450 type II (including 21-hydroxylase, 17α-hydroxylase 17,20 lyase and aromata

6. Remoção de corante disperso não fixado de fibras de poliéster através de uso de enzimas oxidoredutases para redução de águas de lavação
A indústria têxtil é considerada altamente poluidora devido ao alto consumo de água e ao lançamento de diversos produtos químicos e corantes nos corpos dágua. Nem todo corante aplicado no tingimento é fixado à fibra necessitando de lavações posteriores para sua remoção. Enzimas oxidoredutases têm sido intensamente estudadas para a descoloraçã

7. The Mycobacterium tuberculosis Rv2540c DNA sequence encodes a bifunctional chorismate synthase
Background: The emergence of multi- and extensively-drug resistant Mycobacterium tuberculosis strains has created an urgent need for new agents to treat tuberculosis (TB). The enzymes of shikimate pathway are attractive targets to the development of antitubercular agents because it is essential for M. tuberculosis and is absent from humans. Chorismate syntha

8. Identificação e validação de marcadores moleculares indel e SNP para lipoxigenases de sementes de soja / Identification and validation of indel and SNP molecular markers for soybean seed lipoxygenases
The oxidative degradation of fatty acids from soybean oil fraction, that occurs during the grain processing, develop a flavor of unripe been that modify the palatability and therefore the acceptability of soybean products, resulting in problems for the food industry. The enzyme lipoxygenases (linoleate: O2 oxidoreductase, EC 1.13.11.12), that catalyses this

9. ImobilizaÃÃo de Xantina Oxidase em Polissiloxano-Ãlcool PolivinÃlico Magnetizado
Xanthine oxidase (xanthine:oxygen oxidoreductase, XOD, E.C. 1.17.3.2) is a relevant molybdenum enzyme in clinical analysis with a well-established structure and mode of action. It has already been immobilized on several matrices such as polyacrylamide gel beads, polyamide-11, Dacron, polyaniline-silicone, modified carbon paste electrode, nanocrystal gold-car

10. Hybrid neural network model for simulating sorbitol synthesis by glucose-fructose oxidoreductase in Zymomonas mobilis CP4
A hybrid neural network model for simulating the process of enzymatic reduction of fructose to sorbitol process catalyzed by glucose-fructose oxidoreductase in Zymomonas mobilis CP4 is presented. Data used to derive and validate the model was obtained from experiments carried out under different conditions of pH, temperature and concentrations of both substr

11. Performance of a pulsed-cap microcolumn for protein extraction
This work presents the results obtained using a microcolumn agitated by pulsed caps, using aqueous two-phase systems formed polyethylene glycol and salts (monobasic and dibasic) potassium phosphate for protein extraction. Proteins used were extracted cytochrome b5 and the enzyme ascorbic oxidoreductase. It was observed that operation of this equipment was st

12. Produção e caracterização parcial de um composto de baixa massa molecular com atividade fenoloxidasica, de Thermoascus aurantiacus
This work involves the phenoloxidase activity (POx) production by the thermophilic fungus Thermoascus auralltiacus. The best conditions for POx activity production in liquid culture were determined. The addition of lignocellulosic and polyssacharides substrates to culture induced high leveI POx activity. The best substrate was the wheat bran which induced be
