1. Papel da trealose na proteção durante o estresse oxidativo causado por cádmio e a resposta adaptativa a este estresse em Saccharomyces Cerevisiae
A poluição por metais pesados é um dos mais sérios problemas ambientais da atualidade devido tanto ao aumento de sua aplicação, como de sua natureza imutável. A importância em se estudar os metais, deve-se aos seus intensos efeitos tóxicos para o homem e todos os outros seres vivos. O cádmio é um metal não essencial e representa um grande potenci

2. Shared control of maltose and trehalose utilization in Candida utilis
Trehalose biosynthesis and its hydrolysis have been extensively studied in yeast, but few reports have addressed the catabolism of exogenously supplied trehalose. Here we report the catabolism of exogenous trehalose by Candida utilis. In contrast to the biphasic growth in glucose, the growth of C. utilis in a mineral medium with trehalose as the sole carbon

3. Trehalase in Conidia of Aspergillus oryzae
Horikoshi, Koki (The Institute of Physical and Chemical Research, Bunkyo-ku, Tokyo, Japan), and Yonosuke Ikeda. Trehalase in conidia of Aspergillus oryzae. J. Bacteriol. 91:1883–1887. 1966.—Trehalases (soluble trehalase and coat-bound trehalase) were found in the conidia of Aspergillus oryzae, and the total activity of the trehalases increased during the

4. Activity and Heat Stability of Trehalase from the Mycelium and Ascospores of Neurospora
Trehalases from the ascospores of Neurospora tetrasperma and the mycelium of N. crassa were compared. Enzymes from both sources have identical electrophoretic mobilities, Km's, responses to pH, immunological reactions, and activities in low-molarity buffers. Because both enzymes are so similar, conclusions about the properties of the ascospore enzyme may, be

5. Purification of the Trehalase GMTRE1 from Soybean Nodules and Cloning of Its cDNA. GMTRE1 Is Expressed at a Low Level in Multiple Tissues1
Trehalose (α-d-glucopyranosyl-1,1-α-d-glucopyranoside), a disaccharide widespread among microbes and lower invertebrates, is generally believed to be nonexistent in higher plants. However, the recent discovery of Arabidopsis genes whose products are involved in trehalose synthesis has renewed interest in the possibility of a function of trehalose in

6. Trehalose synthesis and metabolism are required at different stages of plant infection by Magnaporthe grisea
The relationship of trehalose metabolism to fungal virulence was explored in the rice blast fungus Magnaporthe grisea. To determine the role of trehalose synthesis in pathogenesis, we identified and deleted TPS1, encoding trehalose-6-phosphate synthase. A Δtps1 mutant failed to synthesize trehalose, sporulated poorly and was greatly attenuated in pathogenic
