1. Determinação de isoflavonas em formulações farmacêuticas / Determination of isoflavones in pharmaceutical formulations
Fitoestrógenos são compostos naturais de origem vegetal com atividade estrogênica. Estão sendo amplamente investigados para a prevenção de doenças crônicas, coronarianas, câncer de próstata e mama, na redução de riscos de osteoporose e alívio nos sintomas da menopausa. Entre os fitoestrógenos já utilizados encontram-se a daidzeína, genisteín

2. Preparação de aminoacidos não proteinogenicos, estruturalmente relacionados ao adoçante natural Monatina
Monatin is a natural amino acid, which exhibits sweetener potency 1400 times bigger than glucose. When mixtured with other sweeteners this compound increases the taste and the flavor of some preparation. This feature increases the biological and commercial importance of Monatin. This amino acid has been isolated from the roots of the south African plant Schl

3. Purificação, caracterização, clonagem e seqüenciamento de β-glicosidades de Tenebrio molitor (Coleoptera) / Purification, characterization, cloning and sequencing of β-glycosidases from Tenebrio molitor (Coleoptera)
In the midgut lumen of Tenebrio molitor larvae there are 4 β-glycosidases (named 1, 2, 3a and 3b), not present in the animal food. They were purified with electrophoresis, ion exchange and hydrophobic chromatographies. β-glycosidase 1 (relative molecular weight - Mr 59,000) is unstable at 30°C but is stabilized by substrates. The enzyme hydrolyses

4. A new mutation in the human lipoprotein lipase gene causing familial hyperchylomicronaemia.
Lipoprotein lipase plays a major role in the regulation of lipid metabolism. The enzyme acts to hydrolyse triglycerides, providing free fatty acids for energy generation or storage, thus affecting the maturation of circulating lipoproteins. Biochemical and molecular analyses were performed on two siblings of consanguineous Pakistani origin, presenting with h

5. The 2 Å crystal structure of leucyl-tRNA synthetase and its complex with a leucyl-adenylate analogue
Leucyl-, isoleucyl- and valyl-tRNA synthetases are closely related large monomeric class I synthetases. Each contains a homologous insertion domain of ∼200 residues, which is thought to permit them to hydrolyse (‘edit’) cognate tRNA that has been mischarged with a chemically similar but non-cognate amino acid. We describe the first crystal structure of

6. Interaction of the Type Iα PIPkinase with phospholipase D: a role for the local generation of phosphatidylinositol 4,5-bisphosphate in the regulation of PLD2 activity
Phosphoinositides are localized in various intracellular compartments and can regulate a number of intracellular functions, such as cytoskeletal dynamics and membrane trafficking. Phospholipase Ds (PLDs) are regulated enzymes that hydrolyse phosphatidylcholine (PtdCho) to generate the putative second messenger phosphatidic acid (PtdOH). In vitro, PLDs have
