1. Inibição da isocitrato liase de Paracoccidioides brasiliensis pelo produto natural argentilactona / Inhibition of isocitrate lyase by Paracoccidioides brasiliensis natural product argentilactone
O fungo Paracoccidioides brasiliensis é o agente etiológico da paracoccidioidomicose (PCM), micose humana sistêmica de maior prevalência na América Latina. Devido à toxicidade dos antifúngicos existentes, e ao aparecimento de isolados resistentes, estudos em busca de novas terapias tem adquirido relevância. Plantas com propriedades terapêuticas repr

2. Inibição da isocitrato liase de Paracoccidioides brasiliensis pelo produto natural argentilactona / Inhibition of isocitrate lyase by Paracoccidioides brasiliensis natural product argentilactone
The fungus Paracoccidioides brasiliensis is the causative agent of paracoccidioidomicosys (PCM), the most prevalent human systemic mycosis in Latin America. The toxicity of drugs and the appearance of resistant strains have imposition the search for new therapeutic approaches. Plants with reputed antimicrobial uses represent a rich source for the screening o

3. Estresse salino e mobilizaÃÃo de reservas cotiledonares durante a germinaÃÃo e estabelecimento da plÃntula de cajueiro anÃo-precoce / Salt stress and reserve mobilization in cotyledons during germination and seedling establishment of precocious-dwarf cashew
This study aimed to obtain basic information on seed germination and seedling establishment of dwarf-precocious cashew (Anacardium occidentale L.) under saline conditions and the relationship between salinity and reserve mobilization during these processes. BRS 189 seeds (cashew nuts) were sown in plastic trays containing vermiculite moistened with distilled

4. CHARACTERIZATION OF E METILISOCITRATO isocitrate Lias Lias The fungal human pathogen Paracoccidioides brasiliensis / CARACTERIZAÇÃO DA ISOCITRATO LIASE E METILISOCITRATO LIASE DO FUNGO PATOGÊNICO HUMANO Paracoccidioides brasiliensis
Paracoccidioides brasiliensis, a thermodimorphic fungus, is the causative agent of paracoccidioidomycosis (PCM), a prevalent systemic mycosis in Latin America. Pathogenicity appears to be intimately related to the dimorphic transition from the hyphal to the yeast form, which is induced by a shift from environmental temperature to the temperature of the mamma

6. phytonematodes; Meloidogyne; RNA interference; gene silencing; Nicotiana tabacum / Isolamento de genes e construção de vetores para o uso no silenciamento gênico de Meloidogyne incognita
Plant parasitic nematodes are responsible for huge economic losses in world agriculture that reaches US$ 125 billion yearly. The most important of these phytopatogens, Meloidogyne incognita, has six developmental stages during the life cycle (egg, four juveniles and female). The juvenile 2 enters the host root via mechanical force and enzymatic degradation t

7. Análise do promotor bidirecional que controla os genes citrato sintase e isocitrato liase do fungo filamentoso Trichoderma reesei. / Analysis of a bidirectional promoter controlling the expression of the citrate synthase and isocitrate lyase genes in the filamentous fungus Trichoderma reesei
O gene TrCit do fungo filamentoso Trichoderma reesei codifica a proteína citrato sintase, uma enzima chave do ciclo de Krebs. Análise da região 5´ upstream de TrCit mostra que o gene está adjacente ao gene TrIcl (que codifica a proteína isocitrato liase, uma enzima do ciclo de glioxalato), em uma orientação cabeça-cabeça. A região promotora interg

8. Effect of glucose on isocitrate lyase in Phycomyces blakesleeanus.
Repression of the synthesis of isocitrate lyase by glucose and/or induction of the synthesis of isocitrate lyase by acetate in Phycomyces blakesleeanus were demonstrated. Both glycerol and ethanol failed to induce isocitrate lyase activity. Furthermore, glucose appeared to cause an in vivo catabolite inactivation of the derepressed enzyme. Isocitrate lyase w

9. Purification and characterization of Acinetobacter calcoaceticus isocitrate lyase.
Acinetobacter calcoaceticus is capable of growing on acetate or compounds that are metabolized to acetate. During adaptation to growth on acetate, A. calcoaceticus B4 exhibits an increase in NADP(+)-isocitrate dehydrogenase and isocitrate lyase activities. In contrast, during adaptation to growth on acetate, Escherichia coli exhibits a decrease in NADP(+)-is

10. Metabolic Role, Regulation of Synthesis, Cellular Localization, and Genetic Control of the Glyoxylate Cycle Enzymes in Neurospora crassa
The glyoxylate shunt enzymes, isocitrate lyase and malate synthase, were present at high levels in mycelium grown on acetate as sole source of carbon, compared with mycelium grown on sucrose medium. The glyoxylate shunt activities were also elevated in mycelium grown on glutamate or Casamino Acids as sole source of carbon, and in amino acid-requiring auxotro

11. Characterization of Saccharomycopsis lipolytica mutants that express temperature-sensitive synthesis of isocitrate lyase.
Four mutants specifically deficient in the activity of isocitrate lyase were independently isolated in the alkane yeast Saccharomycopsis lipolytica. Genetic analysis by means of protoplast fusion and mitotic haploidization revealed that the mutations were recessive and non-complementary at a single genetic locus, icl. icl is a structural gene for isocitrate

12. The Effects of Octanoate and Oleate on Isocitrate Lyase Activity during the Germination of Pinus pinea Seeds 1
The changes of isocitrate lyase levels with respect to the catabolism of triglycerides have been studied during the germination of Pinus pinea seeds. We studied the effects of octanoate, oleate, and inhibitors of protein synthesis on isocitrate lyase during germination. Pyruvate kinase, glucose-6-P-dehydrogenase, malate dehydrogenase, and isocitrate dehydrog
